Secure your code, cloud, and runtime in one central system. Aikido’s all-in-one security platform is loved by developers and security teams alike with full security visibility, insight in what matters most, and fast/automatic vulnerability fixes. Teams get security done with Aikido thanks to: - False-positive reduction - AI Autotriage & AI Autofix - Deep integration into the dev workflow (from IDEs and task managers to CI/CD gating) - AI Pentests - Automated Compliance Aikido covers the entire Software Development Lifecycle (SDLC), including: static application security testing (SAST), dynamic application security testing (DAST), infrastructure-as-code (IaC), container scanning, secrets detection, open source license scanning (SCA), cloud posture management (CSPM), runtime protection, AI pentests, and more.

Astra’s Pentest is a comprehensive penetration testing solution with an intelligent automated vulnerability scanner coupled with in-depth manual pentesting. On top of 10000+ tests including security checks for all CVEs mentioned in the OWASP top 10, and SANS 25, the automated scanner also conducts all tests required to comply with ISO 27001, HIPAA, SOC2, and GDPR. Astra offers an interactive pentest dashboard that the user can use to visualize vulnerability analyses, assign vulnerabilities to team members, and collaborate with security experts. And if the users don’t want to get back to the dashboard every time they want to use the scanner or assign a vulnerability to a team member, they can simply use the integrations with CI/CD platforms, Slack, and Jira.

Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability. Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence.
