Penetration Testing for Small Businesses
& SMEs

What is SME Penetration Testing?

SME Penetration Testing is a specialized security assessment designed to identify critical vulnerabilities in small business networks without the enterprise overhead. It combines automated scanning with manual human exploitation (Gray Box) to deliver cost-effective, audit-ready evidence for ISO 27001, SOC 2, and PCI-DSS compliance.


Scope of Work

Comprehensive Web & Infrastructure Testing

We secure your digital estate by testing the external perimeter, internal networks, and critical web applications against modern threats.

Unlike generic vulnerability scans that just list potential issues, our service delivers audit ready penetration test reports. These reports are specifically written to speak the language of external auditors—clearly demonstrating your technical security posture, validation of controls, and remediation efforts.

  • Web App Testing: OWASP Top 10 coverage (SQLi, XSS, Broken Auth).
  • Internal Infra: Lateral movement & privilege escalation checks.
  • External Infra: Firewall & exposed service validation.
Designed for Auditors

Our reports separate technical data for developers from executive summaries for compliance officers.

Regulatory Alignment

Achieve Global Compliance Standards

ISO 27001

Satisfies Annex A.12.6.1 by providing independent technical verification of your vulnerability management process.

PCI-DSS

Meets Requirement 11.3 for annual internal and external penetration testing of the Cardholder Data Environment.

SOC 2

Verifies the Security Trust Service Principle for SaaS providers, proving to clients that your platform is hardened.

GDPR

Supports Article 32 compliance by testing the effectiveness of technical measures to ensure security of processing.

Our Approach

Which Testing Methodology Do You Need?

We offer Black, White, and Gray box testing. However, for 90% of SMEs seeking compliance, there is one clear winner for cost-efficiency.

We Recommend: Gray Box

The SME Gold Standard. Gray Box testing strikes the perfect balance between depth and speed. By providing our testers with credentials and network diagrams, we skip the time-wasting "reconnaissance" phase.

This allows us to simulate a compromised insider or breached perimeter scenario immediately. You get deeper testing of your critical assets for every dollar spent, ensuring auditors see a comprehensive assessment rather than just a surface-level scan.

Black Box (Not Recommended for SMEs)

Simulates a blind external hacker. While realistic, it forces testers to spend billable hours just finding your IP addresses. High cost, lower ROI for compliance.

White Box (Overkill)

Full access to source code and configs. Extremely thorough but time-consuming and expensive. Usually reserved for enterprise product development.

Why Manual Testing Matters

Don't confuse a cheap scan with a real test.

Feature Automated Vulnerability Scan Manual Gray Box Pentest
Testing Depth Surface Level (Known Signatures) Deep Dive (Logic & Chained Exploits)
False Positives High (Requires verification) Zero (Manually Verified)
Business Logic Testing × No Yes
Audit Compliance (ISO/PCI) Partial Full Satisfaction
Cost Efficiency (ROI) Low (Data without context) High (Actionable Evidence)

Real-World Findings

We don't just rely on tools; we apply years of experience to find what software misses.

70%

of SME internal networks we tested in 2025 had weak SMB signing, allowing attackers to move laterally without passwords.

40%

of environments were compromised via default credentials on ignored IoT devices or printers.

Frequently Asked Questions

How much does a penetration test cost for a small business?

Costs vary based on scope (number of IPs, web pages, and roles), but Solid Cyber offers fixed-price packages tailored for SMEs. By utilizing Gray Box methodology, we eliminate wasted hours, offering enterprise-grade results at a fraction of the cost of large consultancies.

How long does the testing process take?

For a typical SME infrastructure, the engagement usually takes between 3 to 5 business days. This includes reconnaissance, manual exploitation, and reporting.

Do you provide a re-test?

Yes. All our compliance packages include a free re-test to verify that you have successfully patched the identified vulnerabilities, ensuring you are fully ready for your audit.
