Tenable Nessus vs. Trellix Endpoint Security ENS

It is an excellent tool for scanning servers, workstations, and network devices to identify missing patches and misconfiguration; we regularly use it to confirm patch effectiveness after the update; it also helps us for preparing audits such as iso 27001, and regulatory requirements, it also helps us to identify open ports and services that violate security.

It provides great web security and will protect your devices against viruses and malware when paired with other security software and hardware. For instance, we have multiple layers of security set up so if McAfee misses something then one of our other barriers will catch the infection or intrusion before it reaches the network. I would not suggest using this product as a standalone agent because I do not think it will be as effective when working by itself. The dashboard also makes it convenient to manage devices, policies, and settings from wherever you are so it's an ideal solution for any IT department to use. I would just suggest using something else as a backup so your network isn't left vulnerable.

• Nessus is best at performing vulnerability scans, in fact, it gives findings and moreover accurate findings of the assessments. It does not do penetration testing or exploit the vulnerabilities because it is concerned about scanning the systems/applications.
• In fact, Nessus has multiple profiles/policies to perform different types of scans such as, scans oriented for PCI-DSS, malware scans, web application scans, bad shell shock detection scan to name a few.
• Nessus has the ability to classify the vulnerabilities into risk-based categories from critical to even informational which I think is one of the things that separates Nessus from other vulnerability scanners.

Incentivized

• Provides high fidelity alerting.
• Allows CSOC analysts to perform forensic triage and alert investigations through containment from a single pane of glass.
• Provides alert telemetry across on-disk and in-memory attacks.
• Supports many additional 'bolt-on' modules to provide additional alert context or capabilities.

• The tool has lots of options for setting up before scanning any device, this methodology could be simplified further with default configuration for various devices predefined, anyhow we can use this technique by making use of policies.
• For advanced users we cannot disable the plugins inside the plugin groups, we can enable the whole set of plugins at a time, for few hundreds its ok, but thousands of plugins are of waste of resource and time.

Incentivized

• The amount of false detections especially the negative ones needed to be reduced.
• It requires more optimization. It tends to make the PCs slower.
• It almost doesn't have the ability to heal. This is very important as we need our sensitive data to be recoverable.
• It doesn't have any free scanning functionality. Our users using personal machines cannot scan in case of an incident. This could be added like Malwarebytes.

Nessus is best and easy to use application for Vulnerabilities finding and reporting, it has multiple platforms and wide scope covering almost all devices for security improvement so far, thus we are very likely to continue its services.

Tenable Nessus is a great product and provides a lot of value, but it is difficult to set up and use and the amount of data it generates can be overwhelming. It does help us prioritize based on the severity of the detection, however there are sometimes mitigating factors that we have implemented that Nessus does not account for, which causes lots of noise in the reports.

So below is my breakdown, Pro's: Centralized Management, Comprehensive Protection and customization. Con's: Initial cost

I haven't needed to contact support yet. But issues are easily solved with a quick internet search which means support and by extension, the larger community are involved and knowledgeable.

The support of product was very good when we initially implemented the solution. We were getting fats replies and could see the customer approach. After a while the level of support was not following the SLA's and the replies were getting very confusing and late.

Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with Metasploit in order to show to the IT managers the importance of the software/hardware hardening.

Unlike Trellix Endpoint Security Symantec Endpoint provides less information about events on the user side. Trellix give an opportunity to see information about virus detection on a user machine as quick as it possible, so we were able to catch the signs of virus propagation early and prevent the spread of damage

• Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners.
• The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan.
• Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews.

Incentivized

• From an auditing standpoint, we can show that our workstations/servers are protected.
• Even though it cant identify more advanced/targeted malware, it is still good to identify the more obvious malware which occurs daily in my enterprise.
• Since it can be easily deployed, the products can easily get deployed on all systems in the environment for optimal anti-malware protection.
