Astra Security vs Tenable Security Center

Astra Security is a cloud platform for continuous penetration testing of web applications, APIs, and cloud infrastructure. Its DAST scanner covers more than 15,000 test cases and supports authenticated scans involving MFA, SSO, and custom authentication flows. PTaaS combines certified human penetration testers with AI-assisted threat modeling, scheduled tests, and free rescans after remediation. API security features discover shadow, dormant, and undocumented APIs and test API-specific attack cases. The cloud scanner supports AWS, Azure, and GCP with more than 400 checks. Integrations include Slack, Jira, Vanta, GitLab, Jenkins, Bitbucket, Azure, and CircleCI. Astra says it is SOC 2 Type II and ISO/IEC 27001 certified, and its Trust Center shares security evidence. Plans include Scanner Lite at $69 a month, Scanner at $199 a month, and annual pentest options. A target is a domain and its site-tree URLs, representing an application, IP, website, or API.
