BestDefense.io
BestDefense
BestDefense runs continuous AI pentesting that validates real exploits on every deploy, writes the fix, and proves vulnerabilities are closed.
Key features
- Continuous Pentesting on Every Deploy: Vortex uses AI-driven attack techniques, testing auth flows, chaining vulnerabilities, and abusing business logic the way an attacker would.
- Proof-Based Validation: Every finding is confirmed with a real exploit attempt before reaching your team, so unexploitable issues aren't reported.
- Automated Patching & Verification: After fixes merge, the original exploit chain reruns on the patched build to confirm the issue is truly closed.
- Compliance Automation: Each closed loop generates timestamped proof automatically mapped to SOC 2, NIST 800-53, ISO 27001, PCI DSS, and CMMC.
Best for
- Continuous Security Validation: Pentesting every code deploy automatically instead of periodic manual audits.
- Audit Readiness: Maintaining always-current compliance evidence for SOC 2 or ISO 27001.
- Vulnerability Remediation: Automatically generating and verifying fixes for proven exploits.
- DevSecOps Integration: Shifting security testing left into the deployment pipeline.
Nylas
Nylas
Unified API to integrate 250+ email, calendar, and meeting providers quickly, with meeting intelligence and agent accounts for AI agents.
Key features
- Unified Connectivity: Connects to 250+ email, calendar, and meeting providers (Gmail, Microsoft, IMAP, Zoom and others) through a single API, removing the need for individual provider integrations.
- Fast Integration: Quickstart tooling and standardized endpoints designed to enable account connection and data sync in roughly five minutes, reducing developer integration time.
- Meeting Intelligence API: Programmatic access to meeting-related data and insights to power summaries, action-item extraction, metadata tagging, and downstream workflows.

- Unified Email & Calendar Management: Read, send, search, create, and modify emails and calendar events across providers using consistent endpoints and data models.
- Provider Abstraction & Token Management: Centralizes provider authentication, token handling, and sync orchestration so applications do not need to implement provider-specific auth and refresh logic.
- Unified API for 250+ email/calendar/meeting providers
- Meeting intelligence and parsing
