Web scanning needs improvement but offers good vulnerability detection
The downside of Qualys Web Application Scanning is that it cannot crawl automatically. If I provide an IP address and a login form, it does basic testing, but it doesn't go deep as IBM AppScan does. If Qualys Web Application Scanning could improve its crawling capability, it would be more user-friendly. Qualys Web Application Scanning does IP-level testing, requiring direct input of credentials, and can only scan a few pages to provide known generic vulnerabilities, which isn't as beneficial from my point of view. The Vulnerability Management also relies heavily on version numbers and will flag vulnerabilities based on the component version, but it doesn't check if a real fix exists, leading to flags on components that actually have workarounds available.

Context-aware code analysis has reduced noise and now improves developer experience with actionable security findings
I have consistently observed that their scan time is an issue for mono repos. Sometimes with their AI-based scanning, when you triage that scan, the scan never completes or finishes(, which makes it difficult. Another consistent issue is that whenever you have a new repo to onboard to the platform, the tool ideally should detect the master branch by default. However, sometimes the tool fails to identify it and will never scan it unless manually somebody looks into it and fixes the issue. Although their support team is really good, this issue was present six or eight months ago during the POC and is still present now. If it is affecting multiple customers, it should be prioritized and fixed. I would say that their integration aspects could have been improved. I see a lot of different security solutions that provide flexibility to the security teams based on Jira project, team divisions, Slack, and all those can be very much easily customized. Semgrep needs to work on the enhancement of their notification capabilities. Currently, they are working on identifying business logic vulnerabilities or privilege escalation vulnerabilities by looking at the code, and they should continue to focus on and improve this effort. Regarding stability, whenever you have a mono-repo which is a very large repository, the scan never finishes or the scan never kicks in. At that time, you have to reach out to the support team and ask them to expand the resources in the back end to fix it. This is an issue I keep seeing often on that platform.

Quotes from Members

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

Pros

"Key features include: Cloud-based, so the installation is not so tedious, easily deployed, highly scalable, and provides comprehensive reporting."
"The most valuable features are scanning analysis and reporting."
"The interface is user-friendly and easy to understand."
"The best thing about this product is that it is really easy to use."
"Automated scanning has significantly improved our web application security management by reducing manual work."
"The most valuable feature of Qualys Web Application Scanning is the effective scanning that can be done."
"The feature that I have found most valuable is the progressive scan. It is good. It's done in 24 hours."
"Qualys WAS' most valuable features are the navigation flow of the UI and the option for a different layer of security (identification and operation through email and mobile)."
"Since implementing Semgrep, I have noticed significant outcomes, for example, I can resolve vulnerabilities that previously took four days in under a day, saving both time and money, thus enhancing our return on investment."
"The feature is easy to use, saves a lot of time, and is streamlined in nature."
"The most valuable feature is the ability to write our custom rules."
"Compared to other competitors in the market, the AI-backed capability is the biggest strength of Semgrep."
"The best part of Semgrep is its ease of integration with CI/CD pipelines and how it is a developer-friendly tool."
"Semgrep flourishes with the SAST, secret scanning, and Software Composition Analysis types of scanning."
 

Cons

"The authenticated scanning feature could be improved by adding support for real-time scanning tokens and authorization tokens."
"The scanner reports a lot of false positives, which is something that needs to be improved."
"It should have better automatic reporting."
"In terms of the Policy Compliance model which they currently have, not all the platforms are being covered. If they could improve on the Policy Compliance model, since there are policies which are benchmarked against it, this will be helpful for us."
"Deployment can be complicated."
"When comparing this solution to Veracode, Veracode has good interactive features and gives a clear understanding of what the vulnerabilities are, which error line of the vulnerability is on and what can be done. It gives interactive features, whereas this solution does not give a clear understanding of where or how to fix the problem."
"They should improve the performance of the security scanning. It should have better performance."
"It is unclear how to build automation on Qualys. We do some automation, but not fully, because working is difficult."
"However, as a tool it is really complex to maintain and to use, and it has a huge price tag."
"There should be more information on how to acquire the system, catering to beginners in application security, to make it more user-friendly."
"I have consistently observed that their scan time is an issue; sometimes with their AI-based scanning, when you triage that scan, the scan never completes or finishes, which makes it difficult."
"I give Semgrep a six out of 10 simply because there are other tools that are better than this out there."
"Semgrep can be improved by making it more user-friendly."
 

Pricing and Cost Advice

"We are on an annual license for the solution and the pricing could be more affordable."
"Try the free trial of the product to understand the basic working mechanisms.​"
"The cost is $30,000 USD for one year to cover WAS (Web Application Security) and the VM (Virtual Machine) security in a company with 200 employees."
"I rate the software’s pricing a six out of ten."
"Licensing was based on the number of assets that you want to scan on your network. You can also do licensing on subscription. On subscription, it is easier and more flexible. You tell Qualys that you want to move from the 1000 to 2000 band or the 3000 or 5000 band, then they will give you the quotation for it. Once you pay for it, applying the licensing is quite easy and effective."
"The product is expensive, at least initially, in comparison to other products in this category."
"We normally purchase an annual license."
"Qualys has an IT-based licensing based on a yearly license, which is a good way of handling it. However, in some cases, when we do the PCI scanning, the host will not like the scanning and we lose the IT license. So, this could be improved."
