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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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

"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"The assessment reports provided by Amazon Inspector have helped me in identifying security vulnerabilities in my cloud applications by giving us a nicely designed dashboard that provides all the security information we need to work on remediation."
"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."
"The scalability of the solution itself is unparalleled."
"The automated vulnerability detection aspect is most valuable."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"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."
"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
"Vulnerability assessment is the most valuable feature in Tenable Nessus, as it provides brief details regarding the vulnerability issues we have in our network."
"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."
"The most valuable feature of Tenable Nessus is the dashboard. They are convenient to use."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"The initial setup is very straightforward."
"I like this solution because it is complete. It can scan and check many types of vulnerabilities. It can also check for compliance."
"It allows me to prioritize efforts and utilize effective technical resources."
 

Cons

"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"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."
"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."
"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."
"One area for improvement in Amazon Inspector is the automation aspect."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"The tool needs to upgrade asset tracking."
"The integration part is not good because five years ago, Tenable Nessus had more integration capability. After that, Tenable changed their policies and strategy."
"Scans aren't done properly and some devices aren't pinged."
"They could make their reporting a little better."
"From my point of view the solution basically is not for the big enterprise."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"The inventory management function in this solution needs improvement."
 

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's priced according to market standards for its services."
"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 pricing is much more manageable versus other products."
"The price of Tenable Nessus is too expensive for each service center."
"This solution is affordable."
"The price is reasonable."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"The product is free."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"We pay approximately $2,500 on a yearly basis."
