Enkrypt AI Guardrails vs Silker AI Mobile Security

Enkrypt AI Guardrails is a runtime layer for controlling risky behavior across AI agents, tools, retrieval-augmented generation, and MCP. It can filter, rewrite, block, or escalate at prompt, retrieval, tool, and output boundaries, and approve or deny tool calls. Covered risks include prompt injection, unsafe tool actions, boundary violations, sensitive-data exposure, jailbreaks, toxic content, and compliance issues. Policies apply to text, image, and audio inputs. The product supports API-first use with existing model stacks, agent hooks or middleware, MCP Gateway, SIEM and ticketing routes, and identity claims such as Okta, Azure AD, and custom JWT claims. Enforcement logs record a policy ID, version, and reason code and can be exported to SIEM. The product page claims latency under 15 milliseconds. Explore is free and includes 50 credits per month and seven-day data retention; Launch starts at $134/mo (annual). Enterprise includes VPC or on-premises deployment and custom retention.

Silker AI Mobile Security protects APIs used by iOS and Android apps and assesses the apps themselves. Its automated static assessment maps findings to the 2024 OWASP Mobile Top 10, assigns a security grade and 0–100 score, and gives remediation for each finding. A scan can begin with an app identifier and store listing, without uploading source code or a binary; deeper binary analysis is listed as forthcoming. Checks cover insecure storage, cryptography, transport security, binary protections, and exposed components. iOS checks include App Transport Security, Keychain storage, App Attest, anti-tampering, and Universal Links. Android checks include manifests, exported components, Keystore and backup settings, cleartext traffic, Play Integrity, and obfuscation. Runtime protection blocks malicious API requests with a 403, rate-limits or bans abusive IPs, and redacts leaking personal information and secrets. It runs on the app’s backend and does not require an app-store release. Scans are retained for release-to-release tracking. Android, iOS, and web access are listed. The free plan is available; paid plans start at $39/mo.
