There are several threat intelligence platforms that do what you're looking for. Among them are a couple of long-timers in the field, Splunk and IBM QRadar.
McAfee ESM has integrations to prioritize, investigate, and respond to threats, and AlienVault is another platform that claims to have a comprehensive security solution with features such as asset discovery, vulnerability assessment, and network and host intrusion detection.
Relatively recent solutions that have gotten a good deal of attention lately include Palo Alto Networks Cortex XSOAR and Microsoft Sentinel. Other players include Securonix Next-Gen SIEM, LogRhythm, and Devo.
To varying extents, these solutions help streamline incident response processes and improve the overall security posture. To varying extents, they all capture security events and alerts and provide a workflow for incident response. They are said to include real-time threat detection, automated investigation, and case management, and to integrate with other security tools. Have a look at SIEM Tools and SOAR Solutions.
I work at a medium-sized financial services firm.
I am currently researching SIEM solutions and would like to understand the difference between SIEM and Next-Gen SIEM solutions.
In addition, I would like to know what are the differences between Gurucul and Wazuh.
Thank you for your help.
"SIEM" and "Next-Gen SIEM" are often used in marketing and may not have a clear definition. Each vendor may have their own interpretation of these terms. The main difference between SIEM and Next-Gen SIEM (often called XDR) is the responsibility for creating security detections. Next-Gen solutions typically offer more pre-built detections and require less maintenance compared to traditional SIEMs, which primarily focus on collecting log data.
Comparing Gurucul and Wazuh, some key differences between the two include:
Wazuh is open-source, while Gurucul's SIEM solution is proprietary.
Wazuh focuses on providing detailed visibility and control over an organization's endpoint security, whereas Gurucul's SIEM solution provides a broader range of security features such as threat intelligence, user behavior analytics, and incident response.
SIEM (Security Information and Event Management) is a security management system that uses software to collect, store, and analyze security-related data from various sources. It provides a centralized view of the security posture of an organization by correlating events from different sources, such as network devices, servers, and applications.
Next-gen SIEM solutions, also known as "modern" or "advanced" SIEMs, build on the basic functionality of traditional SIEMs by adding new capabilities such as:
- Machine learning and artificial intelligence to improve threat detection and reduce false positives
- Cloud-based deployment for greater scalability and flexibility
- Integration with other security tools such as endpoint protection and vulnerability management
- Automated incident response and threat hunting
- Greater visibility into modern technologies such as cloud environments and IoT devices.
In summary, Next-gen SIEMs offer more advanced analytics, automation, and improved scalability, to help with detecting and responding to cyber threats in real time.
Wazuh is an open-source security platform that provides an integrated solution for threat detection, incident response, and compliance. It is built on top of Elastic Stack and provides an agent-based architecture for data collection and centralized management. Wazuh focuses on providing endpoint security by monitoring and alerting system activity, file integrity, and vulnerabilities.
Gurucul, on the other hand, is a security analytics platform that uses machine learning and behavioral analytics to detect and respond to cyber threats in real time. It also provides a centralized view of security-related data and can integrate with a variety of security tools. Gurucul focuses on providing user and entity behavior analytics (UEBA) and fraud detection, it can identify anomalies and suspicious activities in an organization's network, applications, and user behavior.
In summary, Wazuh is an open source endpoint security platform, while Gurucul is a security analytics platform that uses machine learning and behavioral analytics to detect and respond to cyber threats in real time.
It is important to retain logs for a significant amount of time in order to be able to investigate and analyze past attacks. This allows security teams to identify patterns and trends that can aid in the detection and prevention of future attacks. The retention period will vary depending on the organization's specific requirements and regulations, but it is generally recommended to keep logs ...
Security Information and Event Management (SIEM) solutions differ significantly from firewalls. While both security solutions are integral components of cybersecurity infrastructure, they have different capabilities, functions, and roles.

Nessus is a remote security scanning tool, which scans a computer and raises an alert if it discovers any vulnerabilities that malicious hackers could use to gain access to any computer you have connected to a network. It also uses the Common Vulnerabilities and Exposures architecture for easy cross-linking between compliant security tools. Nessus can be deployed on Cloud, On-premise and stand-alone as in laptop for consulting practice. You can try nessus for 7 days.
While ArcSight is an SIEM. a platform of an integrated set of products for collecting, analyzing, and managing enterprise event information.
I would think their difference lies on how they approach security. Nessus acts as preventive security control in term of identifying vulnerable systems which can exploited maliciously if no actions are done to fix and patch those system with identified vulnerabilities. While arcSight strenght lies on detecting those attacks while on going by correlating different events from different sources like networks packets and log sources from servers and network devices.
For me, SIEM solution is a very indispensable network solution that can really boost your network security stature when deployed and managed properly. But i would put caution when deploying an SIEM solution.
SIEM solution depends on EPS (events per second), and these EPS license are very expensive. If you miscalculated your EPS requirements and deploy the SIEM solution with loower EPS than your network generates, the risks that your SIEM solution may not be able to capture those critical events and correlates those incident properly is high because a lot of those events which are beyond your EPS license will just be dropped by the system.
While nessus will also depend on how many IP or devices you are license to scan. But if you opt to go for unlimited IP or devices I think is not that expensive. Their pro version starts at $2k i am not sure if this is good for unli IP.
Nessus is a Vulnerability Scanner (Made by Tenable who also make SIEM Software) Arcsight is a SIEM (Security Incident Event Manager) made by HP.
Nessus is used by security testers to audit a network and will produce a list of known vulnerabilities sorted by risk, such as this is a Windows 2008 server with the following 5 missing patches, or this is a Cisco router with the public snmp community enabled. - It costs about $300 and takes 20 minutes to set up and 30 mins to scan a small network (give or take).
A SEIM like Arcsite is a log collection server on steroids, you configure all your devices to send all their logs to a central host that can then be configured to correlate those logs, for example if an attacker is scanning your website with Nessus, Arcsite would see connections from the firewall, page loads from the webserver logs, and the webserver requesting data from a database.. In theory you could create an automated action to alert your sysadmins, and block the user at the firewall and email his ISP to tell them he was being naughty. - It costs a fortune and takes about 2 years and 10 people to get it up and running, and then it takes another year to train your employees to use it, then the following years are spent replacing them when they use their new found Arcsite skills to get higher paid positions elsewhere.
Short answer Nessus is a vulnerability scanner, it scans servers/desktops for OS vulnerabilities. ArcSight is a log consolidation, correlation and analysis engine that is basically used to consolidate logs from your Network devices, IDS, IPS, Firewalls and Servers to monitor and detect anomalous traffic and behavior.
Nessus is designed to be a vulnerability management tool. It's primary use is to scan systems to detect known vulnerabilities in ports, services and protocols.
Arcsight is and always has been a SIEM. That means that it is designed to collect and analyze logs from systems to look for known and custom developed indicators of actual malware or "anomolous" behavior as defined by the Archsight administrators. Think of it as something that ingests log data from systems and searches for issues.
Hope this helps. Please let me know if you need additional guidance.
Both are important piece of complete security infrastructure solution, but they don't belong to the same product family or type.
Arcsight is the HP solution for SIEM.
Nessus = isTenable Vulnerability scanner (VS).
They are both part of the leaders in their respective area.
So if you forget about vendors and brands, we can simply say that VS helps identify vulnerabilities in network device and servers. it help to get clear idea about the current picture of the vulnerabilities of our assets and and can be integrated with ticketing systems and / or patch management solution to ensure good follow-up.
SIEM is central point for log management , correlation and event management, depending on the deployments , to get the basic events or logs the SIEM relies on different security components including firewalls/VPN, IDS/IPS, UTM, Endpoint protections, LDAP/ directories, routers, switches, other server type like SQL database, .....
VS like Nessus can also feed the SIEM with information related to assets like OS / software components and versions, vulnerabilities, ..... this information help tune the SIEM to deliver more accurate information to SOC analyst who interface differently with it : Dashboard, reporting, ticketing interfaces, SIRT .....
There are huge link fo useful links to get basic understanding of the two products.
Hope this help.
ArcSight is a log collection and correlation tool set with a monitoring front end, known as a Security Information and Event Management tool. Nessus is a vulnerability scanner, which has the ability to find systems on your network and determine their vulnerability level from informational to critical.
Nessus compliments ArcSight, in that you can take vulnerability data from Nessus and import it into ArcSight. ArcSight can then use that data to provide what is called an asset model - a list of IP addresses, system versions, vulnerabilities, etc. - for increased monitoring capabilities. If I have a system in my asset model that is currently vulnerable to... let's say Heartbleed, and someone attempts to exploit the vulnerability on that system, my IPS will pick up the attack and send the alert info to ArcSight. ArcSight will see that the system is vulnerable to this attack, and if the attack is not blocked it will have a higher criticality.
This is a very broad question and the differences are huge.
In a nutshell:
- ArcSight (HP) provide a SIEM,
- Tenable Network Security provide a Vulnerability Scanner called Nessus.
NESSUS is a remote security scanning tool, which scans a computer and raises an alert if it discovers any vulnerabilities that malicious hackers could use to gain access to any computer you have connected to a network.
ArcSight solutions help customers identify and prioritize security threats, organize and track incident response activities, and simplify audit and compliance activities
What i know Nessus is focus on VA only. Tenable has SIEM solution
Arcsight can do a correlation from log, so it can give you an alert that you need to inspect more detail
look forward more discussion
ArcSight is an (SIEM) Security Information and Event Management system that analyzes and correlates. It is designed to analyzing large amounts of network data in real time. It uses heuristic analysis to identify patterns of normal and abnormal behavior
Nessus is an open-source network vulnerability scanner it is used the signature to Detect security holes in local or remote hosts, and missing security updates and patches.
ArcSight is a cyber security company that provides big data security analytics and intelligence software for security information and event management and log management solutions.
ArcSight SIEM solutions help safeguard your business by providing you complete information security across your IT infrastructure.
Nessus is a remote security scanning tool, which scans a computer and raises an alert if it discovers any vulnerabilities that malicious hackers could use to gain access to any computer you have connected to a network.
You can use Nessus to find machines with vulnerabilities, but I would not categorize it as a SIEM product. Arcsight is a full blown solution which includes a logger and correlation engine.
I don't know Nessus, but
Nessus - vulnerability scanner,
ArcSight = SIEM(Security Information Event Management).
ArcSight can collect, analyse and correlate events gathered from different sources(for example nessus).
