How We Selected These Companies
Choosing a penetration testing provider is a high-stakes decision. A poor choice means you pay thousands of dollars for a scanner output with a cover page. A good choice means you receive a report that identifies real attack paths, satisfies auditors and protects your business.
We evaluated Canadian penetration testing companies based on five criteria: depth of testing methodology, transparency of pricing, relevant certifications held by actual testers, target market fit and track record of delivering actionable results. This list includes firms ranging from boutique specialists to global enterprises because the right choice depends entirely on your organization's size, budget and risk profile.
1. Sherlock Forensics
Location: Vancouver / Burnaby / Coquitlam, BC
Size: Boutique specialist
Target market: SMBs, startups, SaaS companies, law firms and organizations that need court-admissible security documentation
Specialties: Web application pentesting, AI-generated code auditing, ShadowTap adversary simulation, digital forensics and expert witness testimony
Sherlock Forensics has been operating for over 20 years. Principal consultant Ryan Purita holds CISSP, ISSAP and ISSMP certifications and has been court-qualified as an expert witness. The firm differentiates itself with fully transparent pricing ($1,500 / $5,000 / $12,000 CAD tiers), a self-serve purchase process and a specialized AI code auditing practice built for the wave of applications generated by tools like Cursor, Bolt and Claude.
Their proprietary ShadowTap methodology simulates real adversary behavior rather than running automated scans. Reports are designed to be court-admissible and auditor-ready. For Canadian SMBs that want a senior-level tester rather than a junior analyst following a script, Sherlock is the standout option.
2. Mandiant (Google Cloud)
Location: Global (Canadian operations through Google Cloud)
Size: Enterprise
Target market: Large enterprises, government agencies and organizations dealing with active breaches
Specialties: Incident response, threat intelligence, red team operations and nation-state threat analysis
Mandiant, now part of Google Cloud, is the firm you call when you are already compromised. Their threat intelligence capabilities are world-class, backed by frontline visibility into active campaigns from APT groups. Their red team engagements are thorough but priced for enterprise budgets. If you are a Fortune 500 company or a government agency, Mandiant belongs on your shortlist. If you are an SMB looking for a web application pentest, they are likely out of scope and out of budget.
3. Coalfire
Location: US-based with Canadian coverage
Size: Large (500+ employees)
Target market: Companies needing compliance-driven pentesting (PCI DSS, SOC 2, FedRAMP, HIPAA)
Specialties: Compliance assessments, cloud security, application testing and PCI Qualified Security Assessor services
Coalfire excels when the primary driver for your pentest is regulatory compliance. They understand audit requirements deeply and produce reports that satisfy specific compliance frameworks. Their testing is methodical and checkbox-driven by design. For organizations that need a pentest primarily to meet PCI or SOC 2 requirements, Coalfire delivers exactly what auditors expect. For organizations seeking adversarial testing that goes beyond compliance, a dedicated offensive security firm may be a better fit.
4. GoSecure
Location: Montreal, QC
Size: Mid-size
Target market: Canadian mid-market companies needing managed security with penetration testing as part of a broader program
Specialties: Managed detection and response, email security, penetration testing and security awareness
GoSecure is a strong choice for Canadian companies that want penetration testing bundled with ongoing managed security services. Their Titan platform combines MDR with periodic assessments. The advantage is continuity: the team monitoring your environment also tests it, which means they understand your infrastructure deeply. The trade-off is that their penetration testing is part of a larger service bundle, which may not suit organizations that need a standalone assessment.
5. Herjavec Group (Cyderes)
Location: Toronto, ON
Size: Large MSSP
Target market: Enterprise organizations needing managed security operations with periodic penetration testing
Specialties: Managed security services, identity management, incident response and compliance advisory
Founded by Robert Herjavec of Shark Tank fame, the Herjavec Group (now operating as Cyderes following a merger) provides enterprise-grade managed security services across North America. Penetration testing is available as part of their broader advisory and managed security programs. Their strength is scale and integration with a full security operations center. For mid-market companies seeking a standalone pentest, the enterprise service model may be more than what is needed.
6. KPMG Canada
Location: National (offices across Canada)
Size: Big Four
Target market: Large enterprises, financial institutions, public sector
Specialties: IT audit, risk management, security advisory, regulatory compliance and incident response
KPMG brings the weight of a Big Four firm to cybersecurity assessments. Their advantage is credibility with boards, regulators and auditors. A KPMG pentest report carries institutional authority. Their teams include experienced offensive security professionals, though engagement teams can vary in seniority. Pricing reflects Big Four overhead. For publicly traded companies or heavily regulated financial institutions, the KPMG name on a report carries significant value. For startups, the pricing and procurement process may be prohibitive.
How to Choose the Right Firm for Your Needs
The best penetration testing company for your organization depends on three factors:
- Budget: Boutique firms like Sherlock Forensics offer transparent pricing starting at $1,500 CAD. Enterprise firms and Big Four consultancies typically start at $25,000+ and require procurement processes.
- Scope: A web application pentest is different from a red team engagement. Choose a firm whose specialty matches your testing needs.
- Output requirements: If you need a report for auditors, choose a compliance-focused firm. If you need court-admissible documentation, choose a firm with expert witness experience. If you need actionable remediation guidance for your developers, choose a firm that writes for technical audiences.
For Canadian SMBs and startups that want transparent pricing, senior-level testers and reports that serve both technical and business audiences, Sherlock Forensics is the clear choice.
