Weekly insights and risk analysis facilitate informed security decisions

I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.

Automated vulnerability assessments continuously enhance security

The most valuable features probably are the ability to do automated vulnerability assessments, which it does with Amazon Inspector version two. It operates continuously, so as soon as resources are created, it scans them for vulnerabilities. This allows me to pinpoint potential security vulnerabilities and provide actionable recommendations relatively quickly. Larger enterprises usually use Inspector to gather all the vulnerabilities, the CVEs, across all accounts in an AWS organization. The enterprises I work for typically have many accounts in their organization, such as thousands of accounts where I am at the moment. It is a way to gather the vulnerabilities that are present on EC2 instances, container images, and Lambda functions.

Provided increased visibility across the organization's servers

The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Zafran is an excellent tool."

"We saw benefits from Zafran Security almost immediately after deploying it."

"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."

"We are able to see the real risk of a vulnerability on our environment with our security tools."

"Zafran has become an indispensable tool in our cybersecurity arsenal."

"The integration of Amazon Inspector with other AWS services has enhanced our security. Security Hub is a major asset because it allows us to centralize data from various AWS services. We can integrate third-party tools as well. It is just a single-click option."

"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."

"The automated vulnerability detection aspect is most valuable."

"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."

"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."

"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."

"The findings dashboards are neat and easy to understand, offering clear demarcations for different types of findings and detailed insights into specific vulnerabilities and their associated instances. It is not a place where everything is dumped together. It offers an easy-to-understand layout."

"The scalability of the solution itself is unparalleled."

More Amazon Inspector pros

"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."

"Scanners and reports using CIS templates ("de-facto" standard, easy to fix and to locate correction tips at documentation), tests against cloud providers, database profiles, several types of telecom devices, and others highly customizable scans."

"The most valuable feature is the installation of Tenable which is incredibly easy."

"The most valuable feature of Tenable Nessus is website scanning."

"It's scalable."

"Nessus gives me a good preview of vulnerabilities and good suggestions for remediation. It's easy to find a description of a given vulnerability and solutions for it."

"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."

"It allows me to prioritize efforts and utilize effective technical resources."

More Tenable Nessus pros

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."

"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."

"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."

"There isn't too much to improve right now. Scanning on demand or as a part of the pipeline versus a post pipeline solution would be good, but it is not a deal breaker by any means."

"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."

"One major area for improvement is remediation. My team works on remediating findings over time, likely using available patches. However, easier integration with Amazon's patching services would be very helpful."

"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."

"The other point is that the reporting features of Inspector need improvement. For example, I am in an organization with millions of CVEs, and getting an overview of all this is challenging."

"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."

"One area for improvement in Amazon Inspector is the automation aspect."

"It has a limited scope. So, AWS Inspector primarily focuses on the security of the EC2 instance. So, if your architecture includes other AWS services, then you may need to use additional tools for your comprehensive security assessment. So that is one con. Another is, like, we have a dependency on agents."

"The pricing point has increased significantly in recent years. The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner."

"In Nessus Professional, the main drawback was that we could have a single-user login password. So it could be better in terms of security."

"I have found it is sometimes difficult to control the Zoom meeting sessions. For example, it is difficult to know who is talking and when trying to mute everyone but the speaker you end up muting everyone. When using multiple screens it is laborious to find the control buttons, such as to start a session. Additionally, when a recording is done I have found it difficult to find them, there should be an easier way to retrieve them."

"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."

"The reports are okay, but the interface is a bit difficult to navigate in some cases."

"We use credentialed scans. They need more permissions and more changes or settings on Windows and Linux."

"We'd like to see the solution embrace more user-friendliness."

"The user interface of Tenable Nessus feels outdated and could be more user-friendly."

Pricing and Cost Advice

Information not available

"It's priced according to market standards for its services."

"The lowest cost would be around $10 for a few small accounts, however, for thousands of accounts, it could be around $5000 to $6000 dollars per month."

"The pricing is very transparent and clear."

"It is scaled as you go. There are probably a certain number of scans per month, and there are tiers. If you're under a certain tier, it is free. The second level is pennies, and then all the way up to like a million. So, it has a tiered pricing program. They're pretty good with your initial scanning, and there is room to scale based on being affordable, but it is fairly cheap. There are no additional costs. They pretty much think about it as a pay-per-scan type model."

"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."

"The product pricing is dynamic and varies based on the specific needs of each project and customer."

"There is an annual license required to use this solution."

"The product is free."

"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."

"The solution is expensive."

"We paid about six thousand dollars per license."

"Tenable Nessus is affordable."
