Explore Algosec's customer success stories to see how organizations worldwide improve security, compliance, and efficiency with our solutions. SANOFI FINDS THE CURE FOR TIME-CONSUMING APPLICATION MIGRATION WITH ALGOSEC Organization Sanofi Industry Healthcare & Pharmaceuticals Headquarters Paris, France Download case study Share Customer
success stories "Using AlgoSec during our data center migration allowed us to give technical project leaders access to all of the rules involved in the migration of their applications, which reduced the IT security team’s time on these projects by 80%. The application was very useful, simple to use and made everybody happy." AlgoSec Business Impact Simplify data center migration projects Reduce rule migration process time by 80% Streamline and improve firewall operations Background A multinational pharmaceutical company, Sanofi, has 112 industrial sites in 41 countries and operations in more than 100 countries. The company’s 110,000 employees are committed to protecting health, enhancing life, providing hope and responding to the potential healthcare needs of seven billion people around the world. Challenge The sensitive nature of Sanofi’s business and its wide ranging global operations require an extensive and well secured network, which currently has 120 firewalls all over the world. In the midst of a data center consolidation project, the company needed to understand how its security devices would be affected by application migrations. Sanofi was also eager to improve change management processes and gain key performance indicators (KPIs) for risk analysis.“Our main concern with the data center consolidation project was to enable various technical project leaders to see the different rules impacting the migration of their applications, and to avoid any outages. For that, we needed pre-migration and post-migration documentation on security,” says Bruno Roulleau, Network Security Architect at Sanofi. “We also needed metrics on the risk associated with different policies on the firewalls.” Solution When looking for a solution, Sanofi evaluated several vendors. “A key point for us was the ability to easily integrate the security devices in our current infrastructure, into the solution. We also wanted detailed reporting that would allow us to delegate policy management to project leaders,” Roulleau notes.Because Sanofi constantly upgrades its devices, its systems need to evolve and incorporate the new devices and rules seamlessly. “We chose the AlgoSec Security Management solution because its graphical interface is very user-friendly, it easily supports new devices and generates detailed reports and metrics on risks,” says Roulleau.Sanofi also appreciated AlgoSec’s flexibility. “AlgoSec is very open to developing new capabilities. We can ask to have some new features available by a certain date and they will deliver on time,” according to Roulleau. For a company with a complex network and rapidly evolving security needs, that responsiveness proved key to the decision to go with AlgoSec. Results Sanofi’s security team is now able to delegate responsibility for rule changes both during migration and on an ongoing basis. “Using AlgoSec during our data center migration allowed us to give technical project leaders access to all of the rules involved in the migration of their applications, which reduced the IT security team’s time on these projects by 80%. The application was very useful, simple to use and made everybody happy,” Roulleau says.Additionally, with AlgoSec’s reports Sanofi can now easily and clearly document the status of their firewalls as well as the impact of any changes on the network throughout the migration project. “We can now generate detailed reports in just three clicks!” Roulleau adds.Furthermore, AlgoSec’s optimization reports enabled Sanofi to clean up its security policies. Because they could clearly see all of the rules and their impact on network security, Roulleau’s team was able to safely eliminate unused and duplicate rules, which increased the efficiency of the firewalls. Those reports also provided insight into the risks associated with the current system and various changes being made. Schedule time with one of our experts

Cyber Attacks & Incident Response How to Use Decoy Deception for Network Protection Matthew Pascucci 2 min read Matthew Pascucci Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 6/30/15 Published A Decoy Network The strategy behind Sun Tzu’s ‘Art of War’ has been used by the military, sports teams, and pretty much anyone looking for a strategic edge against their foes. As Sun Tzu says “All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.” Sun Tzu understood that to gain an advantage on your opponent you need to catch him off guard, make him believe you’re something you’re not, so that you can leverage this opportunity to your advantage. As security practitioners we should all supplement our security practices with this timed and tested decoy technique against cyber attackers. There are a few technologies that can be used as decoys, and two of the most common are honeypots and false decoy accounts: A honeypot is a specially designed piece of software that mimics another system, normally with vulnerable services that aren’t really vulnerable, in order to attract the attention of an attacker as they’re sneaking through your network. Decoy accounts are created in order to check if someone is attempting to log into them. When an attempt is made security experts can then investigate the attackers’ techniques and strategies, without being detected or any data being compromised. Design the right decoy But before actually setting up either of these two techniques you first need to think about how to design the decoy in a way that will be believable. These decoy systems shouldn’t be overtly obvious, yet they need to entice the hacker so that he can’t pass up the opportunity. So think like an attacker: What would an attacker do first when gaining access to a network? How would he exploit a system? Will they install malware? Will they perform a recon scan looking for pivot points? Figuring out what your opponent will do once they’ve gained access to your network is the key to building attractive decoy systems and effective preventive measures. Place it in plain sight You also need to figure out the right place for your decoys. You want to install decoys into your network around areas of high value, as well as systems that are not properly monitored with other security technologies. They should be hiding in plain sight and mimicking the systems or accounts that they’re living next to. This means running similar services, have hostnames that fall in line with your syntax, running on the same operating systems (one exception is decoys running a few exploitable services to entice the attacker). The goes the same for accounts that you’ve seeded in applications or authentication services. We decided that in addition to family photos, it was time to focus on couples photoshoot ! Last fall we aired our popular City Photoshoot Tips & Ideas and as a result, gave you TONS of ideas and inspiration. And last but not least, you need to find a way to discretely publicize your applications or accounts in order to attract the attacker. Then, when an attacker tries to log in to the decoy applications or accounts (which should be disabled) you should immediately and automatically start tracking and investigating the attack path. Watch and learn Another important point to make is that once a breach attempt has been made you shouldn’t immediately cut off the account. You might want to watch the hacker for a period of time to see what else that he might access on the network. Many times tracking their actions over a period of time will give you a lot more actionable information that will ultimately help you create a far more secure perimeter. Think of it as a plainclothes police officer following a known criminal. Many times the police will follow a criminal to see if he will lead them toward more information about their activities before making an arrest. Use the same techniques. If an attacker trips over a few of carefully laid traps, it’s possible that he’s just starting to poke around your network. It’s up to you, while you have the upper hand, to determine if you start remediation or continue to guide them under your watchful eye.

Atruvia (formerly Fiducia IT AG) Reduces Security Risks For Banks With Algosec Organization Atruvia Industry Technology Headquarters Karlsruhe, Deutschland Download case study Share Customer
success stories "AlgoSec’s Security Management Solution is incredibly powerful. Its intelligent process improvements have directly translated into the highest level of security and compliance for our customers’ networks" Background With over 45 years’ experience in the banking sector, Atruvia ( formerly Fiducia IT AG) is one of the top ten IT providers in Germany. Today, Atruvia manages the IT networks of nearly 1,100 banks, constituting more than 100,000 PC workstations, 6,600 servers and 25,000 self-service banking terminals. Responsible for ensuring the smooth and secure processing of more than 16 billion transactions per year for its customers, Atruvia’s risk mitigation and regulatory compliance strategies are of utmost importance. Challenge To protect its customer networks, Atruvia implemented a number of security solutions, including 60 Check Point and 20 Juniper firewall clusters. However, managing multiple firewalls in a multi-vendor environment proved challenging. “Performing vulnerability assessments for such a large and complex firewall environment was extremely time-consuming, labor-intensive and prone to human error,” says Lutz Bleyer, Atruvia’s Chief Information Security Officer. With multiple stakeholders at each of its client organizations, Atruvia required a structured change management process to prevent firewall policies from growing unmanageable and creating security risks. “We needed a proven firewall management and workflow solution to eliminate potential security risks while providing us with complete visibility into our customer networks, anytime, anywhere,” says Bleyer. Solution After an in-depth analysis, Atruvia chose the AlgoSec Security Management Solution to optimize its security, compliance and change management processes. “AlgoSec provided the most comprehensive, intelligent automation solution for our firewall operations, helping us increase efficiency while improving risk mitigation and compliance,” says Bleyer. Results AlgoSec’s topology-aware technology provides Atruvia with complete visibility into the security landscape of its customers’ networks. “AlgoSec’s in-depth visibility enables us to easily create a hierarchy profile and establish a competency baseline of operations for each networks’ firewalls, even when multiple vendor technologies are involved,” says Bleyer. Atruvia’s security consultants and auditors are now closely aligned with their customers’ IT teams, regardless of their location. “The level of visibility AlgoSec provides across our customers’ security networks, and the ability to perform coordinated tasks remotely with them, enables us to work hand-in-hand as a joint team,” says Bleyer. Atruvia also uses AlgoSec to automate policy change management across customers’ firewall environments, enabling the company to eliminate manual and inefficient processes associated with the security policy change lifecycle, save time and reduce the potential for human error. “AlgoSec has fundamentally changed how we manage sophisticated, multi-device, multi-vendor firewall environments. By automating our workflows, we’ve eliminated unnecessary policy changes and reduced the time required to process changes by half,” explains Bleyer. “Thanks to AlgoSec’s intelligent automation, we’ve gained valuable optimization capabilities enabling our teams to operate smarter and faster.” Another important AlgoSec feature is its automatic assessment and reporting capabilities, which help Atruvia ensure that it remains in continuous compliance with corporate governance rules and adheres to regulatory standards, including ISO 27001, ISO 27002 and Sarbanes-Oxley (SOX). Data and network security, particularly within the financial sector, requires incredible focus on risk management and mitigation. “With AlgoSec we can now analyze every change and its impact on the network before it is live, and focus on risk mitigation rather than crisis management.” In summary, Bleyer commented, “Not only does AlgoSec more than measure up from a technology perspective, but the integrity of the company and its employees has surpassed our expectations and raised the bar for what we look for in other partners.” Schedule time with one of our experts

Network Security Top 9 Network Security Monitoring Tools for Identifying Potential Threats Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 2/4/24 Published What is Network Security Monitoring? Network security monitoring is the process of inspecting network traffic and IT infrastructure for signs of security issues. These signs can provide IT teams with valuable information about the organization’s cybersecurity posture. For example, security teams may notice unusual changes being made to access control policies. This may lead to unexpected traffic flows between on-premises systems and unrecognized web applications. This might provide early warning of an active cyberattack, giving security teams enough time to conduct remediation efforts and prevent data loss . Detecting this kind of suspicious activity without the visibility that network security monitoring provides would be very difficult. These tools and policies enhance operational security by enabling network intrusion detection, anomaly detection, and signature-based detection. Full-featured network security monitoring solutions help organizations meet regulatory compliance requirements by maintaining records of network activity and security incidents. This gives analysts valuable data for conducting investigations into security events and connect seemingly unrelated incidents into a coherent timeline. What To Evaluate in a Network Monitoring Software Provider Your network monitoring software provider should offer a comprehensive set of features for collecting, analyzing, and responding to suspicious activity anywhere on your network. It should unify management and control of your organization’s IT assets while providing unlimited visibility into how they interact with one another. Comprehensive alerting and reporting Your network monitoring solution must notify you of security incidents and provide detailed reports describing those incidents in real-time. It should include multiple toolsets for collecting performance metrics, conducting in-depth analysis, and generating compliance reports. Future-proof scalability Consider what kind of network monitoring needs your organization might have several years from now. If your monitoring tool cannot scale to accommodate that growth, you may end up locked into a vendor agreement that doesn’t align with your interests. This is especially true with vendors that prioritize on-premises implementations since you run the risk of paying for equipment and services that you don’t actually use. Cloud-delivered software solutions often perform better in use cases where flexibility is important. Integration with your existing IT infrastructure Your existing security tech stack may include a selection of SIEM platforms, IDS/IPS systems, firewalls , and endpoint security solutions. Your network security monitoring software will need to connect all of these tools and platforms together in order to grant visibility into network traffic flows between them. Misconfigurations and improper integrations can result in dangerous security vulnerabilities. A high-performance vulnerability scanning solution may be able to detect these misconfigurations so you can fix them proactively. Intuitive user experience for security teams and IT admins Complex tools often come with complex management requirements. This can create a production bottleneck when there aren’t enough fully-trained analysts on the IT security team. Monitoring tools designed for ease of use can improve security performance by reducing training costs and allowing team members to access monitoring insights more easily. Highly automated tools can drive even greater performance benefits by reducing the need for manual control altogether. Excellent support and documentation Deploying network security monitoring tools is not always a straightforward task. Most organizations will need to rely on expert support to assist with implementation, troubleshooting, and ongoing maintenance. Some vendors provide better technical support to customers than others, and this difference is often reflected in the price. Some organizations work with managed service providers who can offset some of their support and documentation needs by providing on-demand expertise when needed. Pricing structures that work for you Different vendors have different pricing structures. When comparing network monitoring tools, consider the total cost of ownership including licensing fees, hardware requirements, and any additional costs for support or updates. Certain usage models will fit your organization’s needs better than others, and you’ll have to document them carefully to avoid overpaying. Compliance and reporting capabilities If you plan on meeting compliance requirements for your organization, you will need a network security monitoring tool that can generate the necessary reports and logs to meet these standards. Every set of standards is different, but many reputable vendors offer solutions for meeting specific compliance criteria. Find out if your network security monitoring vendor supports compliance standards like PCI DSS, HIPAA, and NIST. A good reputation for customer success Research the reputation and track record of every vendor you could potentially work with. Every vendor will tell you that they are the best – ask for evidence to back up their claims. Vendors with high renewal rates are much more likely to provide you with valuable security technology than lower-priced competitors with a significant amount of customer churn. Pay close attention to reviews and testimonials from independent, trustworthy sources. Compatibility with network infrastructure Your network security monitoring tool must be compatible with the entirety of your network infrastructure. At the most basic level, it must integrate with your hardware fleet of routers, switches, and endpoint devices. If you use devices with non-compatible operating systems, you risk introducing blind spots into your security posture. For the best results, you must enjoy in-depth observability for every hardware and software asset in your network, from the physical layer to the application layer. Regular updates and maintenance Updates are essential to keep security tools effective against evolving threats. Check the update frequency of any monitoring tool you consider implementing and look for the specific security vulnerabilities addressed in those updates. If there is a significant delay between the public announcement of new vulnerabilities and the corresponding security patch, your monitoring tools may be vulnerable during that period of time. 9 Best Network Security Monitoring Providers for Identifying Cybersecurity Threats 1. AlgoSec AlgoSec is a network security policy management solution that helps organizations automate and orchestrate network security policies. It keeps firewall rules , routers, and other security devices configured correctly, ensuring network assets are secured properly. AlgoSec protects organizations from misconfigurations that can lead to malware, ransomware, and phishing attacks, and gives security teams the ability to proactively simulate changes to their IT infrastructure. 2. SolarWinds SolarWinds offers a range of network management and monitoring solutions, including network security monitoring tools that detect changes to security policies and traffic flows. It provides tools for network visibility and helps identify and respond to security incidents. However, SolarWinds can be difficult for some organizations to deploy because customers must purchase additional on-premises hardware. 3. Security Onion Security Onion is an open-source Linux distribution designed for network security monitoring. It integrates multiple monitoring tools like Snort, Suricata, Bro, and others into a single platform, making it easier to set up and manage a comprehensive network security monitoring solution. As an open-source option, it is one of the most cost-effective solutions available on the market, but may require additional development resources to customize effectively for your organization’s needs. 4. ELK Stack Elastic ELK Stack is a combination of three open-source tools: Elasticsearch, Logstash, and Kibana. It’s commonly used for log data and event analysis. You can use it to centralize logs, perform real-time analysis, and create dashboards for network security monitoring. The toolset provides high-quality correlation through large data sets and provides security teams with significant opportunities to improve security and network performance using automation. 5. Cisco Stealthwatch Cisco Stealthwatch is a commercial network traffic analysis and monitoring solution. It uses NetFlow and other data sources to detect and respond to security threats, monitor network behavior, and provide visibility into your network traffic. It’s a highly effective solution for conducting network traffic analysis, allowing security analysts to identify threats that have infiltrated network assets before they get a chance to do serious damage. 6. Wireshark Wireshark is a widely-used open-source packet analyzer that allows you to capture and analyze network traffic in real-time. It can help you identify and troubleshoot network issues and is a valuable tool for security analysts. Unlike other entries on this list, it is not a fully-featured monitoring platform that collects and analyzes data at scale – it focuses on providing deep visibility into specific data flows one at a time. 7. Snort Snort is an open-source intrusion detection system (IDS) and intrusion prevention system (IPS) that can monitor network traffic for signs of suspicious or malicious activity. It’s highly customizable and has a large community of users and contributors. It supports customized rulesets and is easy to use. Snort is widely compatible with other security technologies, allowing users to feed signature updates and add logging capabilities to its basic functionality very easily. However, it’s an older technology that doesn’t natively support some modern features users will expect it to. 8. Suricata Suricata is another open-source IDS/IPS tool that can analyze network traffic for threats. It offers high-performance features and supports rules compatible with Snort, making it a good alternative. Suricata was developed more recently than Snort, which means it supports modern workflow features like multithreading and file extraction. Unlike Snort, Suricata supports application-layer detection rules and can identify traffic on non-standard ports based on the traffic protocol. 9. Zeek (formerly Bro) Zeek is an open-source network analysis framework that focuses on providing detailed insights into network activity. It can help you detect and analyze potential security incidents and is often used alongside other NSM tools. This tool helps security analysts categorize and model network traffic by protocol, making it easier to inspect large volumes of data. Like Suricata, it runs on the application layer and can differentiate between protocols. Essential Network Monitoring Features Traffic Analysis The ability to capture, analyze, and decode network traffic in real-time is a basic functionality all network security monitoring tools should share. Ideally, it should also include support for various network protocols and allow users to categorize traffic based on those categories. Alerts and Notifications Reliable alerts and notifications for suspicious network activity, enabling timely response to security threats. To avoid overwhelming analysts with data and contributing to alert fatigue, these notifications should consolidate data with other tools in your security tech stack. Log Management Your network monitoring tool should contribute to centralized log management through network devices, apps, and security sensors for easy correlation and analysis. This is best achieved by integrating a SIEM platform into your tech stack, but you may not wish to store all of your network’s logs on the SIEM, because of the added expense. Threat Detection Unlike regular network traffic monitoring, network security monitoring focuses on indicators of compromise in network activity. Your tool should utilize a combination of signature-based detection, anomaly detection, and behavioral analysis to identify potential security threats. Incident Response Support Your network monitoring solution should facilitate the investigation of security incidents by providing contextual information, historical data, and forensic capabilities. It may correlate detected security events so that analysts can conduct investigations more rapidly, and improve security outcomes by reducing false positives. Network Visibility Best-in-class network security monitoring tools offer insights into network traffic patterns, device interactions, and potential blind spots to enhance network monitoring and troubleshooting. To do this, they must connect with every asset on the network and successfully observe data transfers between assets. Integration No single security tool can be trusted to do everything on its own. Your network security monitoring platform must integrate with other security solutions, such as firewalls, intrusion detection/prevention systems (IDS/IPS), and SIEM platforms to create a comprehensive security ecosystem. If one tool fails to detect malicious activity, another may succeed. Customization No two organizations are the same. The best network monitoring solutions allow users to customize rules, alerts, and policies to align with specific security requirements and network environments. These customizations help security teams reduce alert fatigue and focus their efforts on the most important data traffic flows on the network. Advanced Features for Identifying Vulnerabilities & Weaknesses Threat Intelligence Integration Threat intelligence feeds enhance threat detection and response capabilities by providing in-depth information about the tactics, techniques, and procedures used by threat actors. These feeds update constantly to reflect the latest information on cybercriminal activities so analysts always have the latest data. Forensic Capabilities Detailed data and forensic tools provide in-depth analysis of security breaches and related incidents, allowing analysts to attribute attacks to hackers and discover the extent of cyberattacks. With retroactive forensics, investigators can include historical network data and look for evidence of compromise in the past. Automated Response Automated responses to security threats can isolate affected devices or modify firewall rules the moment malicious behavior is detected. Automated detection and response workflows must be carefully configured to avoid business disruptions stemming from misconfigured algorithms repeatedly denying legitimate traffic. Application-level Visibility Some network security monitoring tools can identify and classify network traffic by applications and services , enabling granular control and monitoring. This makes it easier for analysts to categorize traffic based on its protocol, which can streamline investigations into attacks that take place on the application layer. Cloud and Virtual Network Support Cloud-enabled organizations need monitoring capabilities that support cloud environments and virtualized networks. Without visibility into these parts of the hybrid network, security vulnerabilities may go unnoticed. Cloud-native network monitoring tools must include data on public and private cloud instances as well as containerized assets. Machine Learning and AI Advanced machine learning and artificial intelligence algorithms can improve threat detection accuracy and reduce false positives. These features often work by examining large-scale network traffic data and identifying patterns within the dataset.
