Eight in Ten Are Sole Practitioners: The Cybersecurity GTM Opportunity Nobody Sees

The Data Point That Reframes the Market

One scope note up front: this article is about the go-to-market practice, which advises firms selling into this market. Sagentix prepares organizations for independent assessment; it is not a 3PAO and does not perform the independent assessment, issue certification, run penetration tests, or operate a security operations centre. The CISSP underwrites both that readiness work and the go-to-market work.

The U.S. IT security consulting industry is forecast to grow from $18.1 billion in 2024 to $22.1 billion by 2032, served by thousands of firms across NAICS 541690 (Other Scientific and Technical Consulting Services) and overlapping advisory codes (P&S Market Research, 2025). Within the worldwide security services segment, a single firm — Deloitte — held 16.6% revenue share in 2024, making it the largest player for the second consecutive year (Deloitte Global, 2025; Gartner, 2025). That is dominant. But look at the other end of the spectrum: the overwhelming majority of management, scientific, and technical consulting establishments are sole practitioners with no employees — in Canadian management consulting, 80.6% of establishments have zero payroll employees (Innovation, Science and Economic Development Canada, 2025). Security consulting sits under the same NAICS 5416 parent (Management, Scientific, and Technical Consulting Services), where sole-practitioner dominance is the structural norm across subcategories (Innovation, Science and Economic Development Canada, 2025).

The market is shaped like a barbell. Giants on one end. Independents on the other. The middle is nearly empty.

Why the Middle Matters

For cybersecurity vendors building their go-to-market strategies, this structural gap creates a category creation opportunity.

The giants (the large professional services firms) offer comprehensive security consulting at partner billing rates, with multi-month engagement minimums. The minimum is the barrier, not the rate — it prices out the buyer who needs one gate cleared rather than a programme.

The independents (sole proprietors) offer specialized expertise at accessible rates but with limited methodology rigor. Deliverables from one-person shops are often opinion-led, not evidence-backed — a pattern consistent with the CMC-Canada Common Body of Knowledge observation that separating data gathering from analysis is a discipline most small practices skip (CMC-Canada, 2025).

The middle — productized, evidence-based cybersecurity advisory — barely exists.

What This Means for Your Positioning

If you're a cybersecurity SaaS company or managed security provider building your GTM strategy, the positioning implication is clear:

1. Don't compete on features. The cybersecurity vendor universe has grown from roughly 467 firms in 2003 to more than 4,000 today, per IT-Harvest's vendor census (Stiennon, 2024). No single vendor holds double-digit share in the broader cybersecurity products market either — Gartner's Market Share report places worldwide market leaders well under 20% share each (Gartner, 2025). When thousands of vendors all claim "AI-powered" and "proactive," feature-based positioning is noise. Compliance-aligned positioning cuts through because compliance is a primary buyer trigger — the Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA) mandates that covered entities report cyber incidents within 72 hours and ransomware payments within 24 hours once its implementing regulations take effect (CISA, 2022), and the SEC already requires public companies to disclose material incidents within four business days under its July 2023 final rule (SEC, 2023).

2. Lead with credentials. In a market where the majority of competitors are sole proprietors without enterprise credentials, certifications function as trust signals. The global cybersecurity workforce gap reached 4.8 million professionals in 2024 (ISC2, 2024). Against that backdrop, CISSP-certified professionals carry a substantial pay premium over non-certified peers (ISC2, 2024). Credential density at the firm level shortens sales cycles because it lets procurement check a box that sole-practitioner competitors cannot.

3. Evidence beats opinion. When a competitor's security assessment is a PDF with no citations, an evidence-backed analysis with regulatory data and APA 7th references doesn't just look better — it is defensible in board meetings and compliance audits. That defensibility matters more in light of Stanford RegLab's controlled study finding that frontier LLMs hallucinate on 58–88% of specific legal queries — from 58% with GPT-4 to 88% with Llama 2 — when asked verifiable questions about random federal court cases (Dahl et al., 2024), and Vectara's open Hallucination Leaderboard tracking roughly 2–24% hallucination rates on document-summarization tasks across commercial and open-source models (Vectara, 2025).

The Growth Trajectory

U.S. IT security consulting is forecast to grow from $18.1 billion in 2024 to $22.1 billion by 2032 (P&S Market Research, 2025), while worldwide security services revenue reached $77.1 billion in 2024 at 9.9% year-over-year growth (Gartner, 2025). Gartner projects global information security spending will reach roughly $287 billion by 2027 (Gartner, 2024). AI-driven security tools are creating entirely new premium service categories. Firms that build evidence-based GTM strategies now will be positioned to capture disproportionate share as the market expands — a pattern I keep seeing in the compliance-led segment across my cross-engagement dataset Sagentix Phase 01 Market Intelligence, 2026.

The window for category creation in the middle of the cybersecurity advisory market is open. It won't stay open forever.

When the bulk of your competitors are sole proprietors and the remaining share is dominated by a handful of large professional services firms, the category you create in between is yours to define.

Where This Leaves You

The middle of the cybersecurity advisory market is where I built Sagentix to operate. 1,412 curated artifacts, 6–8 week delivery, CA$4.5K–$45K end-to-end, 18-check quality gate between every phase Sagentix GTM Methodology, 2026. I advise cybersecurity vendors on go-to-market, and Sagentix separately prepares organizations for independent assessment. Sagentix prepares organizations for independent assessment; it is not a 3PAO and does not perform the independent assessment, issue certification, run penetration tests, or operate a security operations centre. That boundary is deliberate.

Cybersecurity founders: which competitor archetype is harder to displace in your deals right now — a large professional services firm on a national framework, or an entrenched independent who has been embedded with your prospect for years?
