Best API Security Software for Windows of 2025

Built on the powerful Graylog Platform, Graylog Security is a leading threat detection, investigation, and response (TDIR) solution that streamlines cybersecurity operations with an intuitive workflow, seamless analyst experience, and cost efficiency. It helps security teams reduce risk and improve key metrics like Mean Time to Detect (MTTD) by optimizing threat detection coverage while lowering Total Cost of Ownership (TCO) through native data routing and tiering. Additionally, Graylog Security accelerates incident response by enabling analysts to quickly address critical alerts, reducing Mean Time to Response (MTTR). With integrated SOAR capabilities, Graylog Security automates repetitive tasks, orchestrates workflows, and enhances response efficiency, empowering organizations to proactively detect and neutralize cybersecurity threats.

Ability to use their favorite local tools such as debugger, IDE, etc. Ability to run large-scale programs that aren't possible locally.

Resurface is a runtime API security tool. Resurface continuous API scanning allows you to detect and respond in real time to API threats and risks. Resurface is a purpose-built tool for API data. It captures all request and response payloads, including GraphQL, to instantly see potential threats and failures. Receive alerts about data breaches for zero-day detection. Resurface is mapped to OWASP Top10 and alerts on threats with complete security patterns. Resurface is self-hosted and all data is first-party. Resurface is the only API security system that can be used to perform deep inspections at scale. Resurface detects active attacks and alerts them by processing millions of API calls. Machine learning models detect anomalies and identify low-and slow attack patterns.

Pynt, an innovative API Security Testing Platform, exposes verified API threats by simulating attacks. We help hundreds companies, including Telefonica, Sage and Halodoc to continuously monitor, categorize and attack poorly secured APIs before hackers do. Pynt’s uses a unique hacking technology and an integrated shift-left strategy, using home-grown attack scenario, to detect real threats. It also helps to discover APIs and suggest fixes for verified vulnerabilities. Pynt is trusted by thousands of companies to protect the No. As part of their AppSec strategies, a number of companies rely on Pynt to secure the no.

Authress, Authorization API to your application. Authorization can be complicated quickly. Even though it seems simple, there are many hidden complications involved in authorization. It is not something you want to do on your own. It takes time to get authorization right. In simple cases, it takes an average of 840 hours to implement authorization logic. This number increases rapidly as you add more features to your app. Your application is your biggest security vulnerability. If you don't have the right skills, your doors are open to malicious attacks. You run the risk of compromising user data, non-compliance to local regulations, and major business losses. Features: Secure authorization API. Instead of creating your own authorization logic, call our API. Written by developers for developers. Granular permissions. Define multiple levels and group them by user role. You can be as specific as you like; Identity provider integrations; Simply call an API to connect any ID provider.
