Linwei Yuan - PeerSpot reviewer
Streamline microservices deployment with integrated execution pipelines and comprehensive monitoring
Harness integrates all functions like execution pipelines, environment checks, and log monitoring in one place. It is very convenient since we have many microservices, so having one platform for all of them is beneficial. The dashboard allows me to monitor all core services' deployment status in one place, making it easier to find bugs and check logs.
Amit Beniwal - PeerSpot reviewer
Simplifies vulnerability discovery and has high quality support
There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores. Sometimes, a vulnerability initially categorized as high severity may be reduced to medium or low over time after security patches are applied. This alignment with the present severity score and CVSS score could be improved.

Quotes from Members

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

Pros

"The features of Harness are valuable, supporting rolling deployments, basic deployments, and blue-green deployments with zero downtime."
"Harness starts integrating with organizations, making everything automated without the need for manual interruption."
"Harness integrates all functions like execution pipelines, environment checks, and log monitoring in one place."
"It's a highly customizable DevOps tool."
"Harness integrates all functions like execution pipelines, environment checks, and log monitoring in one place, making it convenient."
"​It has improved my organization with faster security tests.​"
"It updates repositories and libraries quickly."
"The ZAP scan and code crawler are valuable features."
"This solution has improved my organization because it has made us feel safer doing frequent deployments for web applications. If we have something really big, we might get some professional company in to help us but if we're releasing small products, we will check it ourselves with Zap. It makes it easier and safer."
"OWASP is quite matured in identifying the vulnerabilities."
"The solution is good at reporting the vulnerabilities of the application."
"The HUD is a good feature that provides on-site testing and saves a lot of time."
"It can be used effectively for internal auditing."
 

Cons

"Even with automation, there's a requirement for manual change requests for approvals."
"When deploying multiple components to multiple environments, like production and BCP, failures sometimes occur. Improvements are needed when deploying one component to one environment."
"When integrating Harness with more than twenty applications in one place, it becomes less stable, causing improvements to be necessary."
"I prefer the previous less compact UI version of Harness, which showed more details on the screen."
"There's also room for improvement in debugging pipeline issues, which can sometimes become complex."
"It would be nice to have a solid SQL injection engine built into Zap."
"It would be beneficial to enhance the algorithm to provide better summaries of automatic scanning results."
"OWASP should work on reducing false positives by using AI and ML algorithms. They should expand their capabilities for broader coverage of business logic flaws and complex issues."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"It needs more robust reporting tools."
