Continuous offensive testing has transformed our cloud security and prioritizes critical fixes
The continuous testing and continuous offensive testing are among the best features that AttackIQ offers, and being able to categorize it based on criticality such as very critical, emergency, high, medium, and low is valuable. AttackIQ allows us to resolve issues much quicker because these issues come in categories, enabling us to prioritize them and fix the emergency issues first. It has definitely reduced response time and improved our discoverability of these issues in the first place.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

Cons

"The initial setup was difficult. It was not straightforward."
"The initial setup was quite difficult and took a long time."
"I would like to see more on the automation side. There should be proper tools and support for automation in Tenable itself."
"The most that Tenable Nessus could improve is its speed because they might have put a lot of effort into compatibility issues that downgrade the speed."
"We use credentialed scans. They need more permissions and more changes or settings on Windows and Linux."
"Some things in the user interface could be better. The user interface could allow more adjustments to plugins. The price could also be better."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"Tenable Nessus could include a broader range of IT assets."
"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"The report for counters is too simple and would be improved by a dashboard."
 

Pricing and Cost Advice

Information not available
"We pay approximately $2,500 on a yearly basis."
"The price of Tenable Nessus could improve, it is expensive."
"I would like to see better discounts."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"I think the price is fairly affordable. It provides a license that is fair."
"The newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
