Sentiment score
8.1
Semgrep scales efficiently for both small and large teams, adapting well to diverse environments with cloud-native features.
My concern remains the lack of deep dive analysis and that it produces similar vulnerability results as other tools such as Nessus based on version checks instead of real impact checks.
Security Officer at a tech vendor with 10,001+ employees
It is licensed for assets, so we just contact the team for additional licenses if needed.
Team Lead, Cyber Security at Uridium Technologies
At one point, there was a limitation on reporting for 100,000 assets at a time.
Senior Security Engineer at Charter Communications
I was able to control it from 10 repositories or 10 services to thousands of repositories in a couple of minutes very simply.
Cloud & Application Security at Sixt SE
This is an open-source tool, so it absolutely does the job, but if you were to implement a tool such as this in an enterprise, this would probably not be scalable.

Sentiment score
7.8
Semgrep generally operates stably, though AI scanning limitations and integration improvements are needed for large repositories.
If there is no master branch or default branch, the tool fails to identify it and will never scan it unless manually somebody looks into it and fixes the issue.
Cloud & Application Security at Sixt SE
Since I have been using it, I have not experienced any downtime.
Angular Developer at Flourish Software
 

Room For Improvement

Qualys Web Application Scanning needs improvements in detection, usability, integration, performance, pricing, and feature set to compete effectively.
Semgrep needs user-friendly enhancements, better documentation, efficient scanning, integration flexibility, AI advancements, and improved notifications and databases.
With the growing reliance on AI, Qualys Web Application Scanning should be updated to handle AI-based applications and LLM-based attacks.
Associate Principal, Software Engineering at LTI - Larsen & Toubro Infotech
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.
Security Officer at a tech vendor with 10,001+ employees
I would like it to be cheaper because it is a bit expensive compared to competitors like Tenable Nessus.
Team Lead, Cyber Security at Uridium Technologies
The UI and additional dashboarding and other details would definitely make the tool more user-friendly and more of a candidate to be implemented in an enterprise.
DevSecOps Security Engineer at a manufacturing company with 10,001+ employees
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.
Cloud & Application Security at Sixt SE
More advanced dependency analysis features in the SCA part and deeper vulnerability databases would be beneficial.
SecOps Engineer at IriusRisk
 

Setup Cost

Qualys Web Application Scanning offers flexible, negotiable pricing, deemed cost-effective but pricey, with discounts for bulk orders.
They offer discounts on bulk licenses, making it cheaper compared to competitors like Veracode DAST.
Associate Principal, Software Engineering at LTI - Larsen & Toubro Infotech
I find it a bit expensive compared to other competitors.

Regarding pricing, I think for personal use, it is costly, but if organizations are ready to pay, then it is fine as they are using it.
Security Officer at a tech vendor with 10,001+ employees
It is basically open-source, so the cost to set up is no cost.
Sr. Project Analyst [Cybersecurity] at a consultancy with 10,001+ employees
It offers very reasonable pricing and costs.

It effectively detects vulnerabilities like the OWASP Top 10 without any issues in reporting.
Senior Security Engineer at Charter Communications
Credential scanning is very effective because it goes in-depth into the system, crawling the pages, and reporting on vulnerabilities.
Team Lead, Cyber Security at Uridium Technologies
Qualys Web Application Scanning is accurate and provides minimal false positives.
Associate Principal, Software Engineering at LTI - Larsen & Toubro Infotech
When you triage with AI, it gathers context around the finding and reduces the noise about 80 to 90 percent of the time, asking you to focus only on findings that really matter.
Cloud & Application Security at Sixt SE
The Software Composition Analysis is the most valuable feature in Semgrep.
DevSecOps Security Engineer at a manufacturing company with 10,001+ employees
The best feature of Semgrep is its ability to highlight high priority issues during scanning, making it critical for developers to address these vulnerabilities promptly.

Featured Reviews

AnkitSharma13 - PeerSpot reviewer
Security Officer at a tech vendor with 10,001+ employees
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.
Manjunath Maneppagol - PeerSpot reviewer
Cloud & Application Security at Sixt SE
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.
