Tenable headquartered in Columbia offers Nessus, a vulnerability scanning and security assessment solution used to analyze an entity's security posture, vulnerability testing, and provide configuration assessments.
Microsoft Defender for Cloud is very good at allowing users to see how their Azure environment is secure through the secure score. The recommendations are an excellent source of the controls that should be in place to ensure a secure environment. There needs to be more protection and features for data security.
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.
detect and respond to security threats in the cloud environment, reducing the risk of data breaches and unauthorized access.
The product assists our organization dealing with sensitive data in achieving and maintaining compliance with data protection rules.
The product provides real-time visibility into the cloud environment, offering insights into ongoing security activities.
It guarantees that security teams can actively handle possible threats by delivering real-time monitoring and notifications, reducing the impact on business operations.
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.
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.
It is a great product that integrates nicely when running an Azure platform and even multi-cloud environment. Not looking for point-solutions but a suite that answers most requirements. It is very comfortable being able to use KQL, workbooks and automation that is native to the azure platform
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.
Just for the fact that there is always room to improve, but at the same time because it gives us that single picture across all Microsoft Stack, including the other dependent stack. I think it's the usability and tying into Sentinel is quite helpful as a reseller for us.
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.
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.
Microsoft Defender for Cloud is definitely the choice with the latest market trend and attacks that are currently happening. Microsoft has been able to safe guard a lot after the recent serious attacks happening globally in the digital world. There is a trust in this software and with the latest updates and machine learning capabilities, Microsoft Defender for Cloud should be the choice.
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.
It simplifies security management and saves time. I'm not sure, but I'm very confident it saved me a couple of paychecks by centralizing the data I need to secure the cloud environment.
I also utilize the inventory overview to monitor my team's activities and verify they are following internal regulations, as well as cost overruns.
The recommendations can be utilized as a valuable instructional tool. I have the team explain why they are receiving them, why they are not following them, and what they are doing differently.
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.
