Vigilant Cybersecurity
Services

Proactive security to keep your business defensible.

Cyber threats evolve continuously. We simulate real-world attacks, uncover what is actually exploitable, and give you a prioritized path to fix it, with retesting included.

Six surfaces

Every environment an attacker can reach.

Network Penetration Testing

Internal and external testing that maps your true attack surface and proves what an intruder could reach.

  • External perimeter enumeration
  • Internal network segmentation testing
  • Active Directory attack paths

Full scope

What each engagement actually covers.

Each practice area is led by testers who specialize in it. We do not hand your cloud environment to a generalist who mostly does web apps.

01 / NET

Network Penetration Testing

Internal and external testing that maps your true attack surface and proves what an intruder could reach.

We enumerate everything exposed to the internet, then work inward the way an attacker does, pivoting between hosts, escalating privileges, and chaining low-severity findings into full domain compromise. You get proof of impact, not a list of open ports.

Scope includes

  • External perimeter enumeration
  • Internal network segmentation testing
  • Active Directory attack paths
  • Privilege escalation and lateral movement
  • Firewall and VPN configuration review
  • Wireless network assessment
02 / WEB

Web Application Testing

Manual, business-logic-aware testing that goes far past the OWASP Top 10 checklist.

Scanners find reflected XSS. They do not find the workflow that lets a standard user approve their own invoice. We test authentication, authorization, and business logic by hand, against your application's actual rules, because that is where the expensive bugs live.

Scope includes

  • Authentication and session management
  • Broken access control and IDOR
  • Injection and deserialization flaws
  • Business logic and workflow abuse
  • Multi-tenant isolation testing
  • Client-side and supply chain risks
03 / API

API Security Testing

REST, GraphQL, and gRPC endpoints tested for the authorization gaps that scanners cannot see.

APIs fail quietly. An endpoint that returns the right data for the wrong user will pass every automated check you run. We test object- and function-level authorization across every role you have, plus rate limiting, mass assignment, and schema introspection.

Scope includes

  • Broken object level authorization (BOLA)
  • Function level authorization gaps
  • Mass assignment and over-permissive schemas
  • Rate limiting and resource exhaustion
  • Token handling, scopes, and JWT flaws
  • GraphQL introspection and query depth abuse
04 / CLD

Cloud Configuration Review

AWS, Azure, and GCP environments reviewed for the IAM and exposure mistakes that cause breaches.

Most cloud incidents are not exotic. They are an over-permissive role, a public storage bucket, or a forgotten access key with production rights. We audit identity, network exposure, logging, and data protection against CIS benchmarks and real attacker tradecraft.

Scope includes

  • IAM roles, policies, and privilege escalation paths
  • Public exposure of storage and compute
  • Network security groups and VPC design
  • Secrets management and key rotation
  • Logging, monitoring, and detection gaps
  • CIS benchmark alignment
05 / MOB

Mobile Application Testing

iOS and Android applications tested on-device, including everything they send home.

A mobile app is a binary you hand to your attacker. We reverse it, inspect what it stores on disk, intercept what it sends, and test the backend it talks to. The most common mobile finding is a mobile-only API endpoint nobody else tested.

Scope includes

  • Static analysis and binary reversing
  • Insecure local data storage
  • Certificate pinning and transport security
  • Runtime manipulation and tampering
  • Backend and mobile-only API testing
  • Platform permission and IPC abuse
06 / AI

AI / LLM Security Testing

Prompt injection, data leakage, and agent abuse testing for systems built on language models.

If your model can read untrusted input and take actions, you have an attack surface most testing programs have no coverage for. We test prompt injection, tool and agent abuse, training data exposure, and the guardrails you believe are holding.

Scope includes

  • Direct and indirect prompt injection
  • Tool, plugin, and agent action abuse
  • System prompt and training data extraction
  • Guardrail and content filter bypass
  • Excessive agency and permission scope
  • RAG pipeline and vector store poisoning
Compliance frameworks

Aligned to the standards your auditor already uses.

Every finding is mapped to the control it affects, so evidence lands in the format your assessor expects rather than as a PDF someone has to translate.

How an engagement runs

Three steps. No surprises, no change orders.

Retesting and remediation support are included in every engagement rather than sold back to you after the report lands.

0130–45 min

Scoping call

We walk your environment together, agree on targets, rules of engagement, and testing windows, then send fixed pricing. No discovery fee, no surprises later.

Scope document & fixed quote
021–3 weeks

Test & report

Testing runs against the agreed scope with a live channel open for critical findings. Anything severe reaches you the day we find it, not at the end. You receive a full report with reproduction steps, business impact, and prioritized remediation.

Full technical & executive report

Remediate & retest

We work with your engineers through remediation, then retest every finding to verify it is actually closed. You get a clean retest report and an attestation letter for customers and auditors.

Don't wait for a breach.

Discover your weaknesses before an attacker does. Scoping calls are free, take about thirty minutes, and end with fixed pricing.
