APIsec vs Burp Suite: which is better?

APIsec is a self-service API security scanner that submits a URL and returns a risk score with prioritized findings. It performs black-box scanning, requires no agents or SDK integration, and completes a scan in under a minute using read-only methods plus text-only POST for LLM probes. Burp Suite provides an intercepting proxy and a broad toolkit for manual and automated testing, supporting intrusive workflows such as active vulnerability scanning that can modify state. For teams that need to validate API behavior without access to source code and that prefer a predictable, non-intrusive assessment, APIsec is the better fit. Teams that require deep protocol manipulation, custom exploit development, or granular session handling will find Burp Suite more appropriate.

APIsec maps findings to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II, with explicit coverage of authentication bypass, JWT misconfigurations, BOLA and IDOR, BFLA and privilege escalation, property over-exposure, input validation issues, rate limiting, data exposure including PII and API keys, encryption and HSTS, SSRF indicators, inventory and versioning issues, unsafe consumption surfaces, and LLM / AI Security probes. Burp Suite supports extensible scanning via plugins and custom scripts, allowing you to tailor checks to specific regulations, but it does not provide predefined mappings to these frameworks out of the box. If you need audit evidence aligned to specific controls without building custom checks, APIsec is the stronger choice for most teams.

With Starter tier and above, APIsec supports authenticated scanning using Bearer tokens, API keys, Basic auth, and cookies, gated by domain verification through DNS TXT records or HTTP well-known files. It enforces a strict header allowlist to limit what is forwarded. Burp Suite can handle complex authentication flows and session handling via its interface, but requires manual setup and ongoing maintenance of intercept rules and macros. For CI/CD pipelines, APIsec offers a GitHub Action that fails the build when the score drops below a threshold, an MCP server for AI coding assistants, and a CLI for scripted execution. If your workflow depends on deep proxy-level customization and manual test crafting, Burp Suite remains relevant.

APIsec operates as a read-only scanner that never sends destructive payloads, blocks private IPs and cloud metadata endpoints, and ensures customer data is deletable on demand. It does not fix, patch, or remediate findings, nor does it perform active SQL injection or command injection testing, which are outside its scope. Burp Suite supports active scanning and a wide range of intrusive tests, making it suitable for comprehensive manual assessments. Teams that want continuous monitoring, scheduled rescans, diff detection, and compliance reporting will benefit from APIsec. Organizations that need the flexibility to design custom attack chains and deep manual testing should retain Burp Suite.

APIsec offers a free tier with three scans per month and CLI access, Starter at 99 USD per month for up to 15 APIs with dashboard and email alerts, Pro at 499 USD per month for up to 100 APIs with continuous monitoring and GitHub Action integration, and Enterprise for unlimited APIs with custom rules and SLA. Burp Suite typically follows a per-user or per-seat licensing model with varying feature sets. For security and engineering teams that want automated, standards-aligned scanning and continuous monitoring with minimal operational overhead, APIsec is the better option. Teams focused on advanced manual testing, custom exploit development, and deep proxy-level control will prefer Burp Suite.
