No documented chain of custody for client vulnerability data

Competing on price vs. specialized expertise and certifications
5
Ignoring compliance consulting (PCI DSS, SOC 2, HIPAA) as complementary revenue

Next Steps to Launch Your Cybersecurity Firm

Form your LLC or corporation in Connecticut — cybersecurity firms need strong liability protection for data breach engagements (filing fee: $120)
2
Obtain relevant certifications — CISSP, CISM, CEH, or CompTIA Security+ are expected by enterprise clients in Connecticut
3
Obtain Cyber Liability and E&O insurance — $2,000–$8,000/year; clients require proof of coverage before contracts
4
Register as a federal contractor (SAM.gov) if targeting government clients — opens access to $15B+ in annual cybersecurity contracts
5
Set up a secure home lab or cloud testing environment for penetration testing practice and tool development
6
Obtain a written authorization policy template for pentest engagements — never test without explicit written permission
7
Join (ISC)² or ISACA for CPE credits, networking, and client referrals in the Connecticut security community
8
Create a Managed Security Service (MSSP) retainer offering — recurring revenue from monthly monitoring clients

Frequently Asked Questions

A cybersecurity consulting firm typically requires $20,000–$55,000 to start, covering certifications ($1,000–$4,000), professional liability and cyber insurance ($2,000–$6,000/year), security tools ($1,000–$4,000/year), and working capital. OSCP certification is the most valuable pen testing credential at $1,499.

OSCP (Offensive Security Certified Professional) is the gold standard for penetration testing. CISSP validates security management expertise. CEH (Certified Ethical Hacker) is widely recognized. For compliance work, CISA, CISM, and CRISC are valuable. Most clients expect at least one major certification.

Penetration tests range from $5,000–$25,000 for web application assessments to $25,000–$100,000+ for full red team engagements. Compliance consulting (SOC 2, PCI DSS) runs $15,000–$50,000 per engagement. vCISO retainers range from $3,000–$10,000/month for fractional CISO services.

You must have written authorization from the system owner before ANY testing — no exceptions. Use a detailed Rules of Engagement document specifying scope, testing windows, and out-of-bounds systems. Many firms use the PTES (Penetration Testing Execution Standard) framework for consistent, defensible methodology.
