For security teams shipping faster than they can hire
Pentest your stack
the way an attacker already does
Autonomous Pentesting platform your team runs, plus deep-dive pentests our experts run. Nothing slips through.

We built Siemba for the world you're actually defending
You're not losing because your team isn't good enough, you're losing because your tools were built for a world that no longer exists. One where code shipped quarterly. And AI didn't write half of it.
Annual testing. Continuous attacks. The math has never worked
Every gap below eventually shows up as a board meeting, an audit failure, or a 3am incident call. The only question is whether you find it first, or they do.
300+ exposure days / year
The breach in month six is still on you.
Annual snapshots leave you exposed
Tests run once. Attackers work every day.
86% of breaches
A clean scan is not a clean bill of health.
Scanners miss what attackers exploit
CVEs surface. Attack chains don't.
7 disconnected tools
You're managing tools, not risk.
Five tools, zero unified view
Separate logins, no shared context.
60% of "fixed" vulns reappear
Closed on paper. Still open in production.
Fixes validated with hope, not proof
Developers mark it closed. Nobody checks.
2.74x vuln rate
Shipping the surface attackers want most.
AI code ships untested
Prompt injection isn't any scanner's job.
6 weeks per cycle
Audit prep never really ends.
Compliance prep takes weeks
Manual mapping before every audit cycle.
You build with AI. So do they
AI has doubled your attack surface. Traditional scanners don't test the half that's new.
The coverage you already expect.
Web apps, APIs, auth flows, business logic, network perimeter. Tested continuously by the platform and available for deep-dive engagement.
- OWASP Top 10, fully covered across 30,000+ automated test cases
- REST and GraphQL APIs, parameter fuzzing, auth bypass
- Business logic flaws, what automation misses
- IDOR, cross-tenant data access, object reference abuse
- External attack surface, shadow IT, forgotten subdomains
The coverage your team needs now.
The surface AI-assisted development created. Traditional tools were never built to test any of this.
- Prompt injection, direct and indirect, system prompt leakage
- MCP server vulnerabilities, exposed tools, privilege escalation
- Agentic AI testing, sub-agent IDOR, tool abuse, escalation chains
- RAG pipeline security, data leakage, poisoning
- OWASP LLM Top 10, fully covered by expert engagements
One platform. Every stage of security testing
From first discovery to verified closure. Four connected capabilities, one subscription.
Fits into the stack you already run.
Your AI Security Officer offering real-time insights and risk-based decision support.
Imminent SSL/TLS Certificates Expiry
8 SSL/TLS certificates will expire in the next 30 days, which could lead to service disruptions and security risks.
Inefficiencies in Vulnerability Remediation Cycles
MTTR for certain critical vulnerabilities exceeds 7 days, indicating inefficiencies in your current remediation process.
Unrestricted Hacker Access Through Unpatched Exploits
10 vulnerabilities allow unauthenticated exploitation and have public exploits already available.
Zero-Day Vulnerabilities Jeopardize Security
Multiple unpatched vulnerabilities could grant attackers unauthorized access to critical systems.
Vulnerabilities Lacking Patches Pose Immediate Risk
Active vulnerabilities identified with no patch currently available, increasing your attack surface.
Vulnerabilities Enable Lateral Movement or Privilege Escalation
A number of new vulnerabilities allow lateral movement across systems and privilege escalation.
One partner. Software you run, experts you schedule
Two separate lines, so you know what your team runs, what we run, and which budget each comes from. Each covers the other's gaps.
The platform you subscribe to.
AI-driven testing across your full attack surface from day one.
- Attack surface mapping, vulnerability assessment, AI-native DAST
- MCP server testing built in, not an add-on
- Every fix revalidated, reappearance flagged
- One-click SOC 2, ISO, PCI, HIPAA, NIST reports
- AI-triaged findings routed to Jira, ServiceNow, Slack, GitHub
PTaaS with in-house testers.
In-house OSCP, CPENT and CEH testers, never a crowd.
- Manual depth on web, API, cloud, MCP, and AI
- OWASP LLM Top 10, depth automation can't reach
- Agentic AI and RAG: sub-agent IDOR, tool abuse, poisoning
- Signed, audit-ready third-party reports
- Verified Closure, expert sign-off on critical fixes
Run your pentest from your AI assistant
Prefer to work from Claude, Cursor, or any MCP client? Siemba is available as an MCP server. Trigger scans, pull findings, and scope engagements without leaving your AI client.
Three steps. From exposed to proven closed
No lengthy onboarding. No procurement bottleneck. No waiting on consultants. Here's what happens when you say yes.
Map your attack surface.
Run a free attack surface scan, results in minutes to hours. Every internet-facing asset mapped the way an attacker would map it.
Test your stack.
Autonomous Pentesting runs continuously on the platform. Add expert pentesters for a compliance window or an ongoing engagement.
Prove every fix.
Every fix retested automatically. Critical fixes signed off by certified engineers. Auditors get the certificate before they ask.
A fix isn't closed until it's proven closed
Fixes reappear. Trust isn't proof. The platform re-tests every fix and flags anything that reappears, unlimited. For critical fixes, certified engineers add Verified Closure: an audit-ready certificate.
Enterprise-grade security isn't a Fortune 500 privilege anymore
Whether you run a fast-growing SaaS, a regulated fintech, or a global enterprise, your team is shipping faster than security can keep up. Here's what that looks like for your function.
Board-ready risk, one number.
Continuous validation, one-click compliance reports, and Verified Closure certificates auditors accept, without growing headcount.
Walking into board meetings with one number, not seven dashboards.
Security in the pipeline.
Continuous DAST wired into your release flow, findings routed to Jira, GitHub, Slack, and ServiceNow. Ships fast, stays safe.
Shipping fast because security fires before production, not after.
Always audit-ready.
Expert engagements that satisfy PCI DSS v4.0.1, CMS ARS, and SOC 2 Type II, plus one-click reports for SOC 2, ISO 27001, PCI DSS, HIPAA, and NIST.
Auditors leaving with the certificate before they finish their coffee.
The outcomes security teams get from Siemba
Questions we hear before every demo
Is Siemba a software product or a professional service?
Does Siemba satisfy an independent third-party pentest requirement?
How is Siemba different from Cobalt, Synack, or the scanner I already have?
How is pricing structured?
Are your pentesters in-house, or a crowdsourced researcher pool?
Can we try before we commit, or run a proof of concept?
What is Verified Closure, and why does it matter?
Do you test AI applications, MCP server, LLMs?
Which compliance frameworks do you support?
How do you handle our data?
Where does Siemba run? Do you support data residency?
