Security has shifted left and now catches vulnerabilities early in our development workflow
There are a few areas for improvement. The first is scan speed. For large repositories, initial scans can be slow. Incremental scanning helps, but full scans still take considerable time. The second thing is the false positive rate. While Auto-Triage is good, it is not perfect. Occasionally, genuine issues get filtered out and real false positives slip through. The third one is remediation guidance. Aikido Security tells you what is vulnerable, but sometimes the fix suggestions are generic. More specific, actionable remediation steps would save developer time. The fourth one is IDE integrations. It currently works best in CI/CD pipelines. A proper VS Code or JetBrains plugin for real-time scanning while coding would be a significant improvement. From a customer point of view, the following things could change. The first thing is documentation for custom rules. Aikido Security allows you to create custom scanning rules, but the documentation for this feature is surprisingly thin. I spent considerable time in community forums and with trial and error just to configure basic custom rules. Step-by-step guides with real-world examples would make this feature much more accessible. The second thing is better Slack and communication integrations. Currently, security alerts come through email and dashboard notifications, but our team lives in Slack. A more configurable Slack integration that sends contextual alerts directly to the relevant developer, not just a generic channel notification, would dramatically improve response time. The third one is historical trend reporting. While Aikido Security shows current vulnerability status well, generating historical reports showing security posture improvement over time is limited. For presenting security progress to management or stakeholders, better exportable trend reports would be very valuable.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Quotes from Members

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

Pros

"Aikido Security saved me several hours each week by automating vulnerability scanning and security checks, reducing the need for manual review and helping me focus on more development."
"Aikido Security nests directly in our development workflow and it catches security issues before they reach production."
"We were able to close 90% of issues with the help of Aikido Security tools, providing a return on investment."
"Aikido Security offers the best features including being very easy to use, allowing even a normal tech person with some hands-on experience to use this tool and clearly get the results they want."
"Since switching to Aikido Security, I have noticed a positive impact on my team's productivity with measurable results, as we now have measurements."
"Aikido Security has positively impacted my organization because we feel more secure, we have a good monitoring system for vulnerabilities, and we are able to show our clients our security posture and the security posture of our internal systems."
"My advice for others looking into using Aikido Security is that if the codebase and everything need to be audited and recorded in a single forum, and if they want a unified solution to scan both the code and the image, they can definitely use it."
"My advice to others looking into using Aikido Security is to get it as soon as possible; right now, it is a very good tool for a very good price, and you will see a return on investment in less than six months."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"The product's most valuable feature is its ability to set up the rules easily."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
 

Cons

"I think Aikido Security could improve by reducing some pricing model. Pricing is quite high for a normal user, and if they can make it a little less, it will be much better."
"However, there was one minor issue that I faced. When I had a UUID for an object in the code, Aikido Security was considering it as a secret key, which it was not."
"The accuracy of Aikido Security's output is still not very high, and there are a few features where they are still lacking behind regarding accuracy."
"There are a few areas for improvement. The first is scan speed; for large repositories, initial scans can be slow, and while incremental scanning helps, full scans still take considerable time."
"Aikido Security can be improved by addressing the lags in the UI and ensuring that updates can be given very quickly and rapidly."
"I think Aikido Security could be improved with more detailed remediation guidance, such as additional beginner-friendly tutorials and enhanced customization for alerts and reporting."
"Regarding Aikido Security's AI accuracy and reliability of output, I think its AI capabilities are all right, but it can miss the point sometimes; it is good to have a fast and cheap overview, but I would not rely 100% on it."
"I think Aikido Security could be improved by addressing its Jira integration, which I feel needs a bit of work."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
