Automated insights streamline data security assessment
For Amazon Inspector, we have many EC2 or virtual machines deployed inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages. As we progress with time, this package needs to be updated for security enhancement, which requires us to uninstall the package, install the new version, and then we should be fine. However, the challenge comes with how to scan all our EC2 instances for security vulnerabilities, which is currently managed by Amazon Inspector. Amazon Inspector can scan EC2 instances or ECR, which is the ECR registry where we can save artifacts Docker images. Amazon Inspector can also scan Docker images uploaded to ECR for Elastic Registry service, and it can scan databases and S3 based on the latest updates. I noticed this from a couple of months ago, and it provides huge benefits for security. Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are causing security concerns. Amazon Inspector can list these security concerns and offer guidance on how we can remediate it by updating the package to a specific upper version or something similar.

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.

Quotes from Members

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

Pros

"The automated vulnerability detection aspect is most valuable."
"The vulnerability discovery is valuable, and they also rank those vulnerabilities for you. So, you could rapidly attack some of the higher, severe vulnerabilities as they pop up, if they do pop up."
"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."
"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."
"It is scanning the whole repository for any sort of vulnerabilities, so it allows us to be more confident in our DevSecOps and not put a lot of folks or attention to it."
"My experience with AWS technical support is very good, I didn't face any specific challenges, and even the documentation of AWS is good for both Microsoft, which is Azure, and AWS."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"Tenable Nessus is good. It's the best vulnerability solution in the industry."
"Tenable Nessus is an absolutely stable and fantastic product."
"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
"I have found the vulnerability assessment and the reports to be useful."
"The most valuable feature is the breadth of vulnerabilities that it finds. It's able to find across a lot of different platforms and operating systems. It's also able to combine local testing with network-based testing."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"A valuable feature of the solution is that it is easy to understand."
"Tenable Nessus has provided increased visibility across the organization's servers."
 

Cons

"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"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 is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"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 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."
"The solution could improve security updates."
"I think the reporting templates could be improved with Tenable Nessus."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"It would be a good idea if they have a simulation of attacks or a use case for finding a new vulnerability or dealing with a zero-day attack."
"Consumes more system resources when it's running."
"One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that."
"Tenable Nessus could improve the price."
"It would be nice for the professional module to include some of the reports available in the expert module."
 

Pricing and Cost Advice

"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."
"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 pricing is very transparent and clear."
"It's priced according to market standards for its services."
"It has a fair cost and very good cost-benefit ratio."
"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"Our organization is huge so our license costs $30,000."
"The solution has free options."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
