Onapsis vs. Tenable Nessus

Onapsis is divided into 4 major components,

1. Assess
2. Comply
3. Defend
4. Control

In assess, it does a whitebox and blackbox testing of the ERP systems that have been added to the Onapsis console. It highlights relevant application issues and automates the process, also provides the solutions to implement the fix. In comply, it provides a governance on the various regulatory compliances which the firm has to follow, as well as provides a firm grip to the audit and ERP admin team. In control, it enables a workflow of 15 pre-defined parameter values within the SAP system and helps monitor, and track the changes made to those parameters. The capabilities are to either block, or request for an approval for changes made to those parameters in addition to just monitoring them. In defend, it goes through the SAP logs; and compares it with a pre-defined ruleset to alert the end-users via email or SIEM tool or both.

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.

• Eliminating the manual process improves the overall accuracy of results and also frees up valuable resources to focus on other different projects.
• Onapsis provides great leverage to our technical teams in order to review in a standardized way of the landscape.
• Onapsis always matches vulnerabilities with useful context and finds possible solutions.
• Onapsis is usually implemented to continuously monitor, and alert us on any issues on the SAP systems. Not only this but implementing Onapsis also eliminates the network on the year-end and month-end audits and helps in making the overall process faster, smooth, efficient as well as accurate.

• 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

• Multiple UIs
• No proper customization of UI log-off
• Tedious setup of Control component
• No proper error messages received

• 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 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.

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.

Honestly, I havent use something like Onapsis before and currently I am not aware if there is something similiar out there. They are one of a kind and is a complete suit, so is unlikelly that someone from outside will appear with a better solution.

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 offers very reasonable packages.
• The customer support of Onapsis is reliable and efficient.
• It is a great platform as it shows a unified and easy-to-read different and complex topics in a simpler way.

• 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.
