SILENTCHAIN Professional is now available. The advanced edition of our AI extension for Burp Suite Professional is generally available at $199 per seat, per year – an annual license with all updates included. If you already run the free Community edition, Professional is the upgrade that turns a detection into a confirmed, exploitable finding.
Community-grade passive analysis reads the HTTP traffic flowing through Burp and reasons about it like an analyst – it tells you where a vulnerability probably is. Professional adds the machinery to prove it. The output changes from “this parameter looks injectable” to “this parameter is injectable, here is the request that proves it.”
Rather watch than read? The demo below shows SILENTCHAIN Professional detecting and actively verifying vulnerabilities in real time inside Burp Suite.

What Professional adds
- Phase 2 active verification – constructs and sends a confirming request, then only marks a finding verified once exploitability is demonstrated, with the request that proves it.
- WAF detection and fingerprinting (24 types) – fingerprints Cloudflare, Akamai, ModSecurity, AWS WAF, Imperva and more and flags the firewall in front of each target; when a WAF is actively blocking, active verification backs off that host to avoid an IP ban.
- 200+ curated payloads across SQLi, XSS, command injection, LFI, SSRF, SSTI, XXE, open redirect, IDOR, LDAP and NoSQL.
- Out-of-band (OOB) testing for blind XSS, SSRF, XXE, RFI and blind SQL injection.
- HTML advisory reports – export a polished report with the exact request and response that proves each finding, ready to hand to a client or a developer.
- 10 AI providers – Burp AI (default), Ollama, OpenAI, GPT-5.5, Claude, Claude Code, Gemini, OpenRouter, Z.ai and Azure AI Foundry. Use a local Ollama model for air-gapped, zero-data-exposure testing.

On-prem by design
A tool that ships your proxy traffic to a third-party model is a non-starter for a lot of teams. Select the Ollama provider and point SILENTCHAIN at a local runtime, and analysis runs entirely on hardware you control. Sensitive fields are best-effort redacted before anything is sent to a cloud provider, so SILENTCHAIN fits engagements with hard data-residency requirements. For more on that principle across the product line, see on-prem vs cloud attack surface management.
A report you can hand to the client
Every verified finding lands in a polished HTML advisory report – executive summary, severity totals, findings grouped by weakness category and CWE, and the exact request and response that proves each issue.
