Overview

What Is Penetration Testing?

Penetration testing is the practice of simulating real-world cyberattacks against your organisation's systems, networks, and applications to identify vulnerabilities before malicious actors exploit them. Unlike automated vulnerability scanning, a professional penetration test involves manual, hands-on exploitation by an experienced consultant who thinks and operates like an attacker.

At Cyber Security Pentesting Inc., every penetration test is conducted by our principal consultant, Arturs Stay, who holds OSCP, OSEP, and CREST certifications with over 20 years of experience in enterprise offensive security. We deliver comprehensive vulnerability assessments and penetration testing (VAPT), cybersecurity assessments, and red team operations for organisations in Toronto, across Ontario, and throughout Canada.

Our Approach

Penetration Testing Methodology

Every penetration testing engagement follows a structured five-phase methodology aligned with PTES (Penetration Testing Execution Standard) and OWASP frameworks. This ensures consistent, thorough results regardless of scope or complexity.

Phase 1
Scoping & Rules of Engagement
We define the engagement scope, targets, testing windows, communication protocols, and emergency stop procedures. You receive a detailed Statement of Work with fixed-fee pricing before any testing begins. No surprises, no scope creep.
Phase 2
Reconnaissance & Threat Modelling
Passive and active reconnaissance to map your attack surface. OSINT gathering, subdomain enumeration, service fingerprinting, technology stack identification, and threat modelling based on your specific industry and risk profile.
Phase 3
Exploitation & Post-Exploitation
Manual exploitation of discovered vulnerabilities to prove real-world impact. Chaining findings together, lateral movement, privilege escalation, and demonstrating what an attacker could actually achieve in your environment. Every critical finding includes proof-of-concept code.
Phase 4
Reporting & Executive Debrief
Dual-audience reporting: technical teams receive precise reproduction steps with remediation guidance. Executives receive a clear risk narrative with business impact context. Every engagement includes a live debrief call walking through all findings.

Phase 5: Remediation Support & Retest — After your team remediates findings, we offer targeted retesting to verify fixes are correctly implemented and the same attack paths are no longer viable. Retesting is available as a separate engagement.

Deliverables

Penetration Testing Reports Built for Two Audiences

Your penetration testing report is the most important deliverable of the engagement. We invest significant time in reporting because a test is only as valuable as the clarity and actionability of its findings.

Technical Report
Every finding includes a detailed description, risk rating, exact reproduction steps with screenshots and proof-of-concept code, affected systems, root cause analysis, and specific remediation guidance. Your security team can reproduce and validate every finding independently.
Executive Summary
A clear, jargon-free risk narrative designed for C-suite, board members, and audit committees. Business impact context, overall security posture assessment, comparison against industry benchmarks, and strategic recommendations — not a dashboard of CVSS scores.
Remediation Roadmap
Prioritised remediation plan ranked by business risk, not just technical severity. Quick wins identified separately from strategic improvements. Each recommendation includes implementation effort estimates to help your team plan resources and timelines.
Live Debrief & Ongoing Support
Every engagement concludes with a live debrief call where Arturs walks through all findings with your technical and leadership teams. Questions answered directly by the practitioner who conducted the assessment. Remediation support available throughout the fix cycle.

Our reports are regularly used by clients to present to auditors, regulators, cyber insurance underwriters, and board audit committees. They are designed to meet the documentation requirements of PCI-DSS, SOC 2, ISO 27001, HIPAA, and PIPEDA compliance frameworks.

The Canadian Threat Landscape

Why Toronto Enterprises Need Penetration Testing

Toronto is Canada's largest business hub and a prime target for cyber threat actors. The city's concentration of financial institutions, healthcare networks, government agencies, and technology companies creates a high-value target environment that attracts sophisticated adversaries including nation-state APT groups, ransomware operators, and financially motivated criminal organisations.

Canadian organisations face unique regulatory requirements under PIPEDA (Personal Information Protection and Electronic Documents Act), provincial privacy legislation, and sector-specific regulations like OSFI guidelines for financial institutions. A professional penetration test validates your security controls against real-world attack scenarios and provides the evidence auditors and regulators require.

The average cost of a data breach in Canada exceeds $5 million. A penetration test is a fraction of that cost and identifies the vulnerabilities attackers would exploit before they get the chance. For Toronto enterprises handling customer data, intellectual property, or financial transactions, regular penetration testing is not optional — it is a business-critical investment in operational resilience.

Frequently Asked Questions

Penetration Testing FAQ

How much does penetration testing cost in Toronto?
+
Penetration testing costs in Toronto typically range from $5,000 to $50,000+ depending on scope, complexity, and engagement type. A focused external network penetration test starts around $5,000–$10,000. Web application testing ranges from $8,000–$20,000. Full red team operations for enterprise environments can exceed $50,000. We provide fixed-fee proposals after a scoping call so there are no surprises.
How long does a penetration test take?
+
A focused external penetration test typically takes 5–7 business days. Internal network assessments run 1–2 weeks depending on the environment size. Web application tests take 1–3 weeks based on application complexity. Full red team engagements operate over 3–6 weeks. All timelines are defined in the Statement of Work before the engagement begins.
What certifications should a penetration testing consultant have?
+
Look for CREST certification (the industry gold standard for penetration testing quality assurance), OSCP (Offensive Security Certified Professional), and OSEP (Offensive Security Experienced Penetration Tester). These are hands-on, exam-based certifications that prove real-world exploitation capability. Arturs Stay holds all three, plus CRTO, CRTE, PACES, and 10+ additional offensive security certifications.
Do you provide penetration testing for PIPEDA compliance?
+
Yes. We deliver penetration testing aligned with PIPEDA requirements as well as PCI-DSS, SOC 2 Type II, ISO 27001, and HIPAA compliance frameworks. Our reports are designed to satisfy auditors while providing actionable technical findings for your security team.
Can you perform penetration testing remotely across Canada?
+
Yes. While we are based in Toronto, we perform penetration testing for organisations across all Canadian provinces. External and cloud assessments are conducted remotely by default. For internal network testing, we can deploy on-site in the Greater Toronto Area or ship a pre-configured testing appliance to any location in Canada.
What is the difference between a vulnerability assessment and a penetration test?
+
A vulnerability assessment uses automated scanning tools to identify known vulnerabilities. A penetration test goes further by manually exploiting those vulnerabilities to demonstrate real-world impact, chaining findings together, and testing business logic flaws that scanners miss. Penetration testing proves what an attacker can actually achieve in your environment.
How often should we conduct penetration testing?
+
At minimum, annually — and after any significant infrastructure changes, application releases, or mergers and acquisitions. Many compliance frameworks (PCI-DSS, SOC 2) require annual penetration testing. Organisations with rapidly changing environments, high-risk profiles, or continuous deployment pipelines benefit from quarterly or semi-annual testing cycles.
What do you deliver after a penetration test?
+
Every engagement includes a comprehensive technical report with exact reproduction steps and remediation guidance for each finding, an executive summary with business risk context for leadership and board presentation, a prioritised remediation roadmap, and a live debrief call walking through all findings with your technical and leadership teams. Reports are designed to satisfy auditors while giving your security team actionable next steps.
Is penetration testing safe for production environments?
+
Yes. Safely operating in production environments is a core competency. We define detailed rules of engagement before every assessment, including out-of-scope systems, fragile systems requiring careful handling, testing windows, and emergency stop procedures. In over 20 years of professional penetration testing, we have never caused unplanned downtime or data loss.
Do you need access to our source code for a penetration test?
+
Not typically. Most penetration tests are conducted as black-box (no prior knowledge) or grey-box (limited credentials provided) assessments, simulating how a real attacker would approach your environment. White-box testing with source code access is available for deeper analysis and is common for web application assessments where maximising coverage is the priority.
What is the difference between a penetration test and a red team engagement?
+
A penetration test is comprehensive and systematic — the goal is to find all vulnerabilities within a defined scope. A red team engagement simulates a real, targeted threat actor operating stealthily toward a specific objective (such as accessing sensitive data or compromising domain admin) while testing your detection and response capabilities. Red team tests your people, processes, and technology simultaneously.
Do you sign NDAs before initial discussions?
+
Yes. We are happy to sign a mutual NDA before any sensitive discussions begin. All initial consultations are treated as confidential regardless of whether a formal NDA is in place. We understand that discussing your security posture requires trust, and we take that responsibility seriously.
Do you provide retesting after we fix the vulnerabilities?
+
Yes. Retesting is available as a separate engagement after your team completes remediation. We verify that findings have been correctly resolved and that the same or similar attack paths are no longer viable. This gives your organisation documented evidence that vulnerabilities were remediated — critical for compliance and audit purposes.
Why should we choose a solo consultant over a large penetration testing firm?
+
When you hire a large firm, your engagement is typically staffed by junior analysts running automated tools. The senior consultant who sold you the engagement rarely touches the keyboard. At Cyber Security Pentesting Inc., every engagement is personally conducted by Arturs Stay — the same OSCP, OSEP, CREST-certified practitioner from kickoff to final debrief. You get senior-level expertise for every hour of the assessment, direct communication with the person testing your systems, and results that reflect 20+ years of hands-on offensive security experience.
