Stability Issues

Sentiment score
6.8
Klocwork is reliable and stable, effectively handling large codebases but requires significant computing power and faster updates.
Sentiment score
7.8
Semgrep is stable but needs improvements in scan completion, integration, and resources, especially for AI-based and large repos.
Installation is easy, and the solution is stable.
Integration Supervisor Lead at a manufacturing company with 5,001-10,000 employees
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
Semgrep is stable, as far as my experience indicates.
Senior Software Engineer 2 at Porch
 

Room For Improvement

Klocwork needs improved language support, flexible reporting, better integration with Agile DevOps, and enhanced static and dynamic analysis.
Enhancing Semgrep with better AI, reduced false positives, clear guidance, integration, and business logic focus boosts user experience and utility.
There are too many warnings, and it requires expertise to determine the correct category for them.
Integration Supervisor Lead at a manufacturing company with 5,001-10,000 employees
Klocwork sometimes provides too many additional warnings which require expertise to manage.
Director - Quality Excellence at a manufacturing company with 501-1,000 employees
We would like Klocwork to connect to Git and notify developers of issues tied to specific commits.
Application Development Team Lead at Miura Pay
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 a real estate/law firm with 501-1,000 employees

Manager, Quality, Functional Safety, Cybersecurity Embedded Processing at a manufacturing company with 10,001+ employees
Experience with compliance improvements and efficiency boosts but static analysis engine shows a need for enhancement
One area for improvement is that when customers use different static analysis tools, they report more issues compared to Klocwork. The static analysis engine of Klocwork has areas that need improvement. Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior. Klocwork should be able to analyze large codebases efficiently, supporting a desktop version for periodic small delta changes before pushing to the server.
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.
