GuardionAI vs Silker AI Mobile Security

GuardionAI provides runtime security and governance for customer-facing AI, autonomous agents, and coding agents. Its gateway evaluates agent and MCP calls inline and can allow, block, or redact actions before they execute. Data protection features identify personal information and secrets, mask or vault-tokenize them before requests leave an organization, and can restore responses for users. Runtime guardrails detect prompt injection, jailbreaks, harmful content, and unsafe tool calls; they can block, redact, or flag actions. A coding-agent plugin monitors tool calls and can stop destructive commands, secret exfiltration, and unauthorized calls before they run. GuardionAI can operate as an inline gateway or through its API, and the maker says this requires no application rewrites. Listed integrations include OpenAI, Claude, Gemini, LangChain, LlamaIndex, LangGraph, Pinecone, AWS, Google Cloud, and Microsoft Azure. The company says its gateway is encrypted, model providers do not see raw data, and customer data is not used to train its models. It describes the service as GDPR-, HIPAA-, and LGPD-ready, with SOC 2 Type II in progress.

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.
