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.

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

"Harness integrates all functions like execution pipelines, environment checks, and log monitoring in one place, making it convenient."

"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."

"You can run it against multiple targets."

"The solution has tightened our security."

"It scans while you navigate, then you can save the requests performed and work with them later."

"It's great that we can use it with Portswigger Burp."

"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."

"The community edition updates services regularly. They add new vulnerabilities into the scanning list."

"Automatic scanning is a valuable feature and very easy to use."

"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."

More OWASP Zap pros

Cons

"There's also room for improvement in debugging pipeline issues, which can sometimes become complex."

"I prefer the previous less compact UI version of Harness, which showed more details on the screen."

"Even with automation, there's a requirement for manual change requests for approvals."

"When integrating Harness with more than twenty applications in one place, it becomes less stable, causing improvements to be necessary."

"When deploying multiple components to multiple environments, like production and BCP, failures sometimes occur. Improvements are needed when deploying one component to one environment."

"It would be beneficial to enhance the algorithm to provide better summaries of automatic scanning results."

"Deployment is somewhat complicated."

"There isn't too much information about it online."

"ZAP's integration with cloud-based CICD pipelines could be better. The scan should run through the entire pipeline."

"When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking."

"It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful."

"For scalability, I would rate OWASP Zap between four to five out of ten."

"The technical support team must be proactive."
