Find the breach
before they do.
Crimson Hex is a cyber security company built around one job: showing you exactly how your applications, APIs, and mobile products can be broken into, then helping you close it and keeping watch after.

What's the difference between a vulnerability scan and a penetration test?
A vulnerability scan, like our recurring Nessus-based scanning, automatically checks for known weaknesses on a schedule. A penetration test goes further: a senior tester manually tries to exploit what's found, chains issues together, and tests business logic that automated tools can't understand. Most teams that ship fast need both: scanning to catch drift between engagements, and manual VAPT to catch what scanning can't.
How long does a typical VAPT engagement take?
Most web, API, or mobile engagements run one to three weeks from kickoff to final report, depending on the size of your attack surface. We give you a specific timeline once we've scoped the target with you.
Do we still need SOC-as-a-Service if we already have a SIEM?
Usually, yes. Having the logs isn't the same as having someone watching them. Our SOC-as-a-Service plugs into the SIEM or logging stack you already run and adds the human triage layer: an analyst reviewing alerts, hunting for anomalies, and escalating only what's actually worth your attention.
What's included in the report we get at the end of a test?
Every finding ships with severity, clear reproduction steps, business impact, and concrete remediation guidance your developers can act on directly, not just a raw scanner export.
Do you offer a free retest after we fix issues?
Yes. Every VAPT, mobile, and code review engagement includes one free retest once your team has patched the reported issues, so you know the fix holds before you close it out.
Will you sign our NDA before a scoping call?
Yes, happy to sign your NDA before any scoping call or engagement begins.
How is pricing determined?
Every engagement is scoped to your actual attack surface first, so we quote a fixed price after a short call rather than using a generic rate card.
Which compliance frameworks can you help with?
Our security consulting service covers readiness guidance for ISO 27001, SOC 2, and PCI-DSS, including the policy and documentation work that goes with it.
Do you configure firewalls to a specific standard like CIS Benchmarks?
Yes. Firewall configuration and hardening is scoped against the CIS Benchmark for your specific platform, then adjusted to your actual traffic patterns and business requirements rather than applied as a generic template.
Built to be the security partner you'd actually recommend
We started Crimson Hex around a simple idea: testing should be manual and expert-led, reports should be built to be fixed rather than filed, and monitoring shouldn't require ripping out the stack you already trust.
What makes an engagement with us different
Senior testers, every time
Your engagement is scoped and run by senior consultants, not routed to whoever's free that week.
Reports built to be fixed, not filed
Every finding ships with reproduction steps, business impact, and a concrete remediation path your developers can act on.
Retest included
Once you've patched, we verify. No engagement is "done" until the fix actually holds.
Monitoring without migration
Our SOC service works with the logging and SIEM setup you already run, so you don't have to rebuild your stack for us.
How a testing engagement runs
Same structure for VAPT, mobile, and code review engagements: scoped up front, with no surprises along the way.
Scope & Plan
We define targets, rules of engagement, and success criteria with your team before any testing starts.
Test
Manual testing against your web app, API, mobile build, or codebase, backed by industry-standard tooling.
Report
A clear findings report covering severity, evidence, business impact, and step-by-step remediation guidance.
Retest & Close
Once fixes are in, we verify them and issue a closure letter you can share with customers or auditors.
Tell us what you're building
Whether it's a one-off VAPT engagement or ongoing SOC monitoring, we'll reply within one business day with next steps.
VAPT for Web & APIs
Manual penetration testing of web applications and REST/GraphQL APIs: OWASP Top 10, business-logic flaws, broken auth, and access-control gaps that scanners miss.
What you get from this engagement
Manual testing of every workflow, not just automated crawl coverage
OWASP Top 10 and API-specific checks (BOLA, broken auth, mass assignment)
Business-logic abuse cases specific to how your product actually works
A findings report with reproduction steps and prioritized fixes
One free retest once your team has patched the reported issues
How we think about vapt for web & apis
We start by mapping how your application actually works, not just crawling for known bug classes. From there we manually attempt to chain lower-severity issues into real impact, the same way an attacker would, rather than reporting every scanner flag in isolation.
Often paired with VAPT for Web & APIs
Mobile App Security
Static and dynamic testing of mobile apps: insecure local storage, weak API communication, reverse-engineering resistance, and platform-specific misconfigurations.
What you get from this engagement
Static analysis of the app binary for hardcoded secrets and weak controls
Dynamic testing of runtime behavior, local storage, and session handling
Review of how the app talks to your backend APIs
Reverse-engineering resistance and tamper-detection checks
Platform-specific configuration review for iOS and Android
How we think about mobile app security
We test the app the way it actually ships: installed on-device, talking to your real or staging backend, under normal and adversarial conditions. Static analysis catches what's baked into the binary; dynamic testing catches what only shows up at runtime.
Often paired with Mobile App Security
Source Code Review
Line-by-line review backed by static analysis tooling. We find the logic and configuration flaws that only show up when a human reads the code, not just runs it.
What you get from this engagement
Static analysis (SAST) pass across the codebase for known weak patterns
Manual review of authentication, authorization, and data-handling logic
Dependency and configuration review for known vulnerable components
Findings mapped to exact file and line, with suggested fixes
Support call with your developers to walk through the report
How we think about source code review
Automated tooling flags the obvious patterns; our reviewers spend the rest of the time on what tools can't judge, like whether an authorization check is actually enforced everywhere it needs to be, not just where it's expected.
Often paired with Source Code Review
SOC-as-a-Service
Already have your SIEM and logging in place? We plug in and monitor: triaging alerts, hunting anomalies, and escalating real incidents around the clock.
What you get from this engagement
Works with the SIEM, EDR, and logging stack you already run
Continuous alert triage by a human analyst, not just automated rules
Anomaly hunting across your log sources for what rules alone miss
Escalation only for what's actually worth your team's time
Monthly reporting on what was seen, triaged, and closed
How we think about soc-as-a-service
We don't ask you to change your stack before we start. We plug into what you already log, spend the first weeks learning what “normal” looks like for your environment, then tune alerting around that baseline instead of a generic rule set.
Often paired with SOC-as-a-Service
Security Consulting & Guidance
Architecture reviews, compliance readiness (ISO 27001, SOC 2, PCI-DSS), security policy design, and incident-response planning for teams building their own program.
What you get from this engagement
Security architecture review for new or existing systems
Compliance readiness guidance for ISO 27001, SOC 2, or PCI-DSS
Security policy and documentation design for your team to adopt
Incident response planning, so you have a plan before you need one
Ongoing advisory access for the questions that come up in between
How we think about security consulting & guidance
We treat compliance frameworks as a floor, not a ceiling. The goal is a security posture that would hold up even if the audit didn't exist, with documentation your team can actually maintain after we're gone.
Often paired with Security Consulting & Guidance
Vulnerability Assessment & Scanning
Recurring, industry-standard scans (Nessus and equivalent tooling) across your network, infrastructure, and web assets. Every finding is triaged and verified by an analyst, so you get a prioritized fix list, not a 400-page PDF of noise.
What you get from this engagement
Recurring scans using industry-standard tooling (Nessus and equivalent)
Coverage across network, infrastructure, and web-facing assets
Every finding triaged and verified by an analyst before it reaches you
A prioritized fix list, not a raw scanner export
Flexible cadence: weekly, monthly, or quarterly, based on your risk profile
How we think about vulnerability assessment & scanning
Scans run on a cadence that matches your release pace, not a fixed calendar. Every result passes through an analyst before it reaches you, so a scanner's false positive doesn't become your team's fire drill.
Often paired with Vulnerability Assessment & Scanning
Firewall Configuration & Hardening
Firewall rule review and configuration measured against CIS Benchmarks, then tuned to how your business actually operates rather than applied as a blind template.
What you get from this engagement
Firewall rule review and cleanup measured against CIS Benchmark controls
Least-privilege rule sets built around your actual traffic patterns
Network segmentation review, so a breach in one zone can't reach everything else
Change documentation your team or auditors can actually follow
Post-hardening validation to confirm rules behave as intended
How we think about firewall configuration & hardening
We start from the CIS Benchmark for your specific firewall platform, then adjust every recommendation against how your business actually operates, because a control that blocks a workflow your team depends on gets disabled within a week anyway.
