Definitions and recommendations come from NIST, the UK's NCSC, OWASP and the text of PCI DSS 4.0.1, reviewed in October 2026.\n- Criteria: the question each approach answers, depth, frequency, scope, false positives, detection, PCI DSS requirements, legal framework, cost and maturity required.\n- Prices are indicative market ranges published by vendors, not our rates.\n- This comparison is not sponsored.\n::\n\n## Four approaches, four questions\n\nA **vulnerability scan** is an automated tool. It probes your systems, compares what it finds against a database of known flaws and produces a list. It doesn't try to get in.\n\nA **penetration test** goes further. The UK's NCSC defines it as a way of gaining assurance in a system's security by attempting to breach its defences, using the same tools and techniques an adversary might. The NCSC adds an important nuance: a test shouldn't be your main way of finding flaws, but rather a check on your vulnerability management, much as an external audit checks the work of an internal finance team.\n\nA **bug bounty** invites outside researchers to report flaws in exchange for a reward, usually money, often through a specialized platform.\n\nA **red team exercise** simulates a realistic attack on the organization's operations to assess its overall security capabilities, as NIST defines it. The aim isn't to find every flaw, but to see whether a targeted attack would go unnoticed.\n\n## The logical order for a small business\n\nThese approaches stack rather than replace one another.\n\n**Start with scans.** They're basic hygiene. PCI DSS 4.0.1, for instance, requires internal and external scans at least every three months, with external scans run by an Approved Scanning Vendor (ASV). A monthly scan followed by patching already solves a large share of problems.\n\n**Then a penetration test.** It confirms what an attacker can actually do. The NCSC notes that a test can only validate the absence of known issues on the day it's run, and that a year or more often passes between tests, which is why scanning in between matters. PCI DSS requires internal and external tests at least every 12 months and after any significant change. The [cost of a penetration test](\u002Fen\u002Fblog\u002Fpenetration-testing-cost-quebec) depends mostly on scope.\n\n**Then, possibly, a bug bounty.** OWASP is blunt about the downsides: plenty of junk reports and false positives, a budget that can climb if flaws are plentiful, researchers who sometimes stray out of scope, and difficulty telling legitimate testing from a real attack. It recommends bounties only for organizations that already have a mature disclosure process.\n\n**Finally, a red team.** It only makes sense if someone is watching your alerts. Without monitoring, the exercise will mostly confirm that nobody is.\n\n## The legal framework\n\nA penetration test or red team exercise requires **written authorization** from the system owner: without it, access can be an offence under the Criminal Code (s. 342.1). The engagement letter sets out the scope, dates, permitted techniques and emergency contacts. For a bug bounty, the program's published rules, with a safe harbour clause, govern what researchers may do; OWASP advises getting legal advice before launching one.\n\nIf you accept credit cards, the PCI DSS questionnaire that applies to you determines what's mandatory; our article on [PCI DSS 4.0.1 for small businesses](\u002Fen\u002Fblog\u002Fpci-dss-4-small-business) helps sort it out.\n\n## How to choose\n\n- **Nothing regular in place yet?** Start with monthly internal and external scans and a process for applying patches.\n- **A client, insurer or PCI DSS wants proof?** A yearly penetration test, plus one after each major change, with a retest of the fixes.\n- **Running a web application or SaaS product, with a team that fixes quickly?** A disclosure policy first, then a private bug bounty program.\n- **You have a SOC or MDR service and solid basics?** A red team exercise will measure whether it all holds together.\n\nFor most Canadian small businesses, the winning combination stays the same: regular scans and a targeted [penetration test](\u002Fen\u002Fservices\u002Fpenetration-testing) at least once a year.\n\n::cta{variant=\"devis\"}\n::\n",{"title":47,"description":285},[364,366,368,370,372,375,378,381,384],{"title":365,"url":306},"NIST SP 800-115: Technical Guide to Information Security Testing and Assessment",{"title":367,"url":320},"NCSC (UK): Penetration testing",{"title":369,"url":334},"OWASP: Vulnerability Disclosure Cheat Sheet (bug bounty programs)",{"title":371,"url":348},"NIST CSRC: definition of 'red team exercise'",{"title":373,"url":374},"Microsoft Learn: PCI DSS requirement 11 (text of requirements 11.3 and 11.4)","https:\u002F\u002Flearn.microsoft.com\u002Fen-us\u002Fentra\u002Fstandards\u002Fpci-requirement-11",{"title":376,"url":377},"Packetlabs: guide to the average cost of a pentest in Canada (August 2026)","https:\u002F\u002Fwww.packetlabs.net\u002Fposts\u002Fguide-to-the-average-cost-of-a-pentest-in-canada\u002F",{"title":379,"url":380},"Stingrai: average cost of a pentest in Canada in 2026","https:\u002F\u002Fwww.stingrai.io\u002Fblog\u002Faverage-cost-of-pentest-canada-2026",{"title":382,"url":383},"Tenable: Nessus Professional (pricing)","https:\u002F\u002Fwww.tenable.com\u002Fproducts\u002Fnessus\u002Fnessus-professional",{"title":385,"url":386},"Criminal Code, s. 342.1: unauthorized use of computer","https:\u002F\u002Flaws-lois.justice.gc.ca\u002Feng\u002Facts\u002Fc-46\u002Fsection-342.1.html","en\u002Fcomparisons\u002Fpentest-vs-scan-vs-bug-bounty","pentest-scan-bugbounty",null,[391,394,397],{"profile":392,"pick":305,"why":393},"15-workstation accounting firm in Mississauga with no particular outside requirement","Monthly internal and external scans followed by patching cover most of the ground at low cost.
