Nessus in for auditing infrastructure

Nessus is one of the best vulnerabilities assessment tools. We use it to evaluate, as one of our primary controls, to know how secure or insecure is our infrastructure (networks, servers, switches configurations) are and also identifying the different vulnerabilities in web applications we use. So with the help of the results (reports), we can explain to the managers and the technologies administrators the risks that exist in their software and hardware. For the company is very useful for the audit areas and security area. Those areas work together in the assessment and evaluation. We trust in the info and results gave by Nessus.
  • Vulnerabilities assessment.
  • Configuration file evaluation.
  • Reporting.
  • Interaction with some other tools like Metasploit.
When you want to know about how strong the hardening of your software is. Also, when installing a router, switch or another network device, Nessus helps you by indicating if the configuration has some vulnerabilities or maybe if it requires some other options to make a strong configuration and avoid attacks.
We dont use the support.

We use Nessus within our information security department to scan our network for vulnerabilities. Afterwards we ensure to patch the necessary vulnerabilities. We also use Nessus for PCI scanning as required for PCI compliance.
  • Vulnerability scanning.
  • PCI scanning.
  • Could use an upgrade within reports.
  • Scans can take a long time to complete. Have to break them down in small sections.
Nessus is great, if not the best, at vulnerability scanning. We use it for PCI scanning as well to ensure we are PCI compliant.
We have never had to contact them. We only contact Tenable when it comes time to renew Nessus.

Without a doubt, one of the best vulnerability scanners on the market

I have used Nessus for performing the vulnerability scans largely. It is largely used for doing vulnerability assessments and penetration testing activities. No matter if you are a security researcher or a security consultant working for some organization, Nessus is known to everyone and is a really helpful tool.
  • 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.
  • Starting with the cost of Nessus, though it is available for free also it has some restrictions for the free version. Nessus essential which is a free version does not allow to perform internal/external PCI scan policies, config audits which I think is a drawback. As many security researchers, small organizations use this tool for vulnerability scans I think some additional features should be added into free version as Nessus professional version is not cost-friendly for everyone.
  • I think Nessus can improve the way it shows scan status while the scan is ongoing. Once scans are started and running, it sometimes failed to show exactly how much percent of scan is completed, for example, it shows scan status from 0% completed to 100% completed directly without showing the in-between completion percentage.
Nessus is perfectly suitable for performing comprehensive vulnerability assessment scans being a vulnerability scanner. It is less appropriate for performing penetration testing since it is not a penetration testing tool, it does not have the ability and modules to exploit the vulnerabilities of the system.
I have not exclusively came across any issue and need to contact Nessus for support of the tool.

Our company personnel are mostly depending on Nessus for performing vulnerability assessment on servers and Network Devices of clients, most of our clients are banking networks, government bodies looking for securing their networks and compliance in accordance with information security standards. Nessus is very advanced tool for mainly highlighting server's configuration level, software level issues and missing security patches and for network devices it lists any configuration issues, outdated practice or patches required for improvement of information security.
  • With Nessus we can find the missing critical patches for a server or workstations.
  • Nessus points out any vulnerable or outdated software Technologies used in the system, thus eliminating any chances for security flaws being turned up.
  • Nessus typically points any configuration level issues in accordance with the OWASP guidelines. Even the configuration of SSL related which are most of the time handled by some vendors or 3rd parties.
  • Nessus not only lists out these Vulnerabilities but describes clearly the vulnerabilities in details with its thousands of plugins updated regularly, the tool also recommends solution with practical details of easy implementation.
  • 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.
Nessus is quite suitable foe any network devices like switches, routers, firewalls or proxy, for different servers also the tool is very operable, it has plugins for almost every operating system and managed devices, only thing is before using on to the intended device the tool should be updated which takes much time to compile plugins.
Though we didn't needed the support from nessus team directly, but the Nessus community has answers to all our questions or issues faced by us can be easily resolved with proper addressing and understanding in no time.

I use Nessus to conduct periodic vulnerability scans of our primary production servers and plan to implement scheduled scans of all nodes in batches at some point in the future.
  • Identifying known vulnerabilities.
  • Scoring discovered vulnerabilities appropriately.
  • Presenting vulnerabilities and remediation recommendations on an easy to read format.
  • While it is easy to use, it assumes a certain level of knowledge from the user, therefore, it could explain things a little better as the user moved through the program.
Nessus is quick and easy to implement as long as the user has some general knowledge of information security and vulnerability scoring.
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.
