DevArmor vs ThreatTree

DevArmor has no write-up on Specifiction yet; its figures are above.

ThreatTree is a browser-based tool for organizing threat models into forests of Data Flow Diagrams and Attack Trees. It scores risks by likelihood and impact, then generates a ranked risk register across the trees in a forest. Threats can be tagged with STRIDE, LINDDUN, OWASP Top 10, CAPEC, and MITRE ATT&CK; mitigations can be mapped to standards including ISO 27001:2022, NIST SP 800-53 Rev 5, CIS Controls v8, PCI DSS v4.0, NIST CSF 2.0, and SOC 2. Teams can invite members with owner, editor, or viewer roles. Reports are available as PDFs, with JSON and STIX 2.1 exports. Optional per-forest AES-256-GCM encryption is available on every plan, including Free. ThreatTree says data is stored on UK servers, connections use TLS 1.2 or higher, and encrypted database backups are taken daily and retained for 30 days. The Free plan costs nothing and has limits on forests and trees. Pro costs $29 a month per user, billed monthly; Enterprise pricing is by quote.
