Two Approaches to Scaling Security Testing
Organizations face an expanding attack surface, tighter regulatory requirements, and growing expectations from customers and stakeholders to safeguard sensitive information.
Against this backdrop, new approaches to security testing continue to emerge with the goal of making testing more continuous, scalable, and cost-efficient.
Two models that have gained prominence are Crowdsourced Cybersecurity and Penetration Testing as a Service (PTaaS). Both aim to identify weaknesses before adversaries do, but they differ substantially in how testing is structured, delivered, governed, and measured.
This white paper examines those differences through executive insights and real-world experience, with the goal of clarifying how each model operates, the risks and benefits it introduces, and where it may fit within an organization’s broader security program.
Crowdsourced Cybersecurity vs. PTaaS
Crowdsourced cybersecurity and Penetration Testing as a Service both seek to uncover vulnerabilities before attackers exploit them, but they differ in how testing is structured, governed, and incentivized.
Quality of Findings
Crowdsourced cybersecurity engages a distributed group of testers, each bringing different backgrounds, experience levels, and testing approaches.
PTaaS uses a defined team of specialists working within standardized methodologies and a consistent testing process.
Trust & Accountability
Crowdsourced programs may include contributors operating under pseudonyms or without direct identification, creating additional questions around accountability and oversight.
PTaaS is carried out by identified security professionals within a defined engagement, with clearer ownership and accountability throughout the testing process.
Incentive Alignment
Crowdsourced programs commonly compensate participants on a per-finding basis, which can place more emphasis on individual vulnerabilities and higher-severity findings.
PTaaS is organized around a defined engagement, allowing testing activity to remain aligned with broader objectives, scope, and organizational risk.
Both models can uncover vulnerabilities. The difference is in how testing is controlled, who is accountable, and what the testing model ultimately incentivizes.
Where Crowdsourced Testing Can Break Down
Crowdsourced security testing can expand coverage, but the model can introduce tradeoffs around finding quality, accountability, and incentives. Explore each risk and how a structured PTaaS model differs.
Quality of Findings
Crowdsourced cybersecurity can offer a wide range of perspectives and insights, but that breadth can also introduce significant variability in the quality of both the testing process and the findings it produces.
The question is whether a broad-based testing model can consistently deliver the high-confidence, actionable findings security teams need to reduce risk.
Skill Disparity
Participants can range from highly skilled professionals to inexperienced testers, creating variability in the depth and quality of findings.
Professional Expertise
PTaaS relies on experienced professionals who follow established testing practices and industry standards.
Standardization Problems
Testing and reporting approaches can vary significantly when contributors follow different methodologies.
Standardized Methodologies
Defined testing methodologies and reporting processes make findings more consistent and repeatable.
False Positives & Negatives
Lower-confidence findings can consume resources while meaningful vulnerabilities may still go undetected.
Ongoing Validation
Retesting and validation help confirm findings and verify that remediation actually reduced the risk.
More findings do not automatically mean better testing. The value comes from accurate, reproducible, actionable findings.
Trust & Accountability
Trust and accountability sit at the core of any security testing program. Crowdsourced approaches can introduce contributors whose identities, motivations, and responsibilities may be difficult to verify.
That lack of transparency can create uncertainty around the credibility of findings, accountability for testing activity, and the protection of sensitive data.
Anonymity of Participants
Some crowdsourcing platforms allow anonymous or pseudonymous participation, making identity and background harder to verify.
Verified Professionals
PTaaS engagements rely on identifiable, vetted security professionals working within defined roles.
Lack of Accountability
Responsibilities for testing quality and handling of findings can be less clearly defined.
Clear Accountability
Defined contracts, scopes, and responsibilities make ownership and accountability explicit.
Potential for Misuse
Access given to unknown contributors introduces additional risk if information is mishandled or activity exceeds the authorized scope.
Trust & Reliability
Identifiable teams and defined access controls provide greater visibility into who is testing and how access is governed.
Security testing requires privileged access. Organizations should know who is testing, what access they have, and who is accountable.
Incentive Alignment
Crowdsourced researchers' incentives may not always align with an organization's broader security priorities, particularly when compensation or recognition is tied to individual findings.
That can encourage attention toward highly visible or highly rewarded vulnerabilities rather than the full set of risks that matter to the organization.
Focus on Rewards
Researchers may prioritize findings that offer the greatest financial reward or recognition.
Alignment With Your Priorities
Testing can be scoped around the organization's critical assets, business context, and security objectives.
Competition Over Collaboration
Competitive incentives can discourage cooperation and lead to fragmented testing activity.
Collaborative Approach
A coordinated team can share context and expertise throughout the engagement.
Short-Term Engagement
Individual researchers may have little ongoing involvement once a finding is submitted or rewarded.
Long-Term Partnership
Continuous testing, remediation support, and retesting create a longer-term relationship focused on reducing risk over time.
Incentives shape what gets tested. The testing model should align activity with organizational risk, not simply the next available reward.
When Trust and Access Break Down
The risks around identity, privileged access, and accountability are not theoretical. Real-world incidents show how trusted access can be abused and how difficult it can be to verify who is actually operating inside an organization.
Privileged Access Misused at HackerOne
One notable incident involved a HackerOne employee who misused privileged access to vulnerability reports.
Operating under a pseudonym, the insider attempted to resubmit findings directly to affected organizations in order to collect bounties.
The incident demonstrates an important distinction: vetting alone does not eliminate insider risk. When individuals have access to sensitive vulnerability information, organizations also need clear controls, monitoring, and accountability around how that access is used.
Vulnerability reports can function as blueprints of organizational weaknesses. Access to them should be identifiable, controlled, and accountable.
The Broader Risk of Identity Verification
Nation-state actors have demonstrated an ability to disguise themselves as legitimate technology professionals and gain access to organizations through normal hiring and contracting processes.
That risk becomes especially relevant in distributed environments where organizations may grant sensitive access to large, decentralized pools of external contributors.
KnowBe4 Hiring Incident
A North Korean operative reportedly passed interviews and background checks using stolen identity information and an AI-enhanced image before attempting to deploy malware after gaining access.
DEV#POPPER Campaign
North Korean actors posed as recruiters and used fake developer opportunities and malicious coding exercises to compromise targets and steal sensitive information.
Broader Infiltration Tactics
U.S. authorities have documented the use of fraudulent freelance profiles and remote job applications as a means of accessing organizations and funding state operations.
Whether the risk comes from a trusted insider or a sophisticated external actor, access without strong identity, oversight, and accountability creates exposure.
Where Crowdsourced Cybersecurity Can Add Value
Crowdsourced testing can be useful in the right context, particularly when broad coverage, diverse environments, and exploratory testing are more important than tightly controlled, repeatable assessment.
Consumer & IoT Device Testing
Crowdsourced testing helps uncover vulnerabilities in smart home and IoT devices across environments that can’t be replicated in a lab.
Niche Hardware & Peripherals
Crowdsourced programs can be effective at testing specialized devices such as printers, gaming accessories, and uncommon hardware configurations.
New App & Feature Rollouts
Large researcher pools can quickly expose logic flaws and abuse scenarios in new consumer app features before they scale.
Public-Facing APIs
Crowdsourced programs can stress-test APIs and reveal weaknesses that surface through unusual inputs, unexpected usage, and unconventional interactions.
Regional & Localization Gaps
Global rollouts can benefit from region-specific testing, helping identify localization issues and environment-specific weaknesses through researchers operating in those markets.
Crowdsourced security works best when applied to broad, exploratory testing challenges where diversity of thought and scale are the greatest assets. It is not a complete solution, but it can be an effective way to complement internal security efforts and increase visibility.
Crowdsourcing and PTaaS Do Not Have to Be Either/Or
“Meridian Cooperative leverages both Crowdsourcing through our Managed Bug Bounty program and Penetration-Testing-as-a-Service (PTaaS). To combat some of the concerns noted in the article regarding Crowdsourcing, Meridian Cooperative selected a private Bug Bounty program so only the top-performing, U.S.-based, background-checked security researchers participate in our Managed Bug Bounty program.
Meridian Cooperative also partners with an industry-leading vendor for its AI-based PTaaS platform that we offer our utilities and leverage in-house. The PTaaS platform helps reduce security risk by autonomously finding exploitable weaknesses and providing detailed remediation guidance. It also allows you to perform internal, external, IAM, AD Password Audits, and Cloud-based penetration testing. Ultimately, the value of the PTaaS platform is in better understanding weaknesses that lead to critical impacts, so you know exactly what to fix in order to disrupt the kill chain.”
The question is not whether crowdsourcing has value. It is where it fits, how tightly it is governed, and what other testing capabilities surround it.
Why Crowdsourced Security Isn’t the Best Way to Scale Testing
Crowdsourced security can expand testing coverage, but scaling it introduces tradeoffs that go beyond vulnerability discovery.
Variable Trust
Open or distributed participation can make identity, accountability, and access harder to govern consistently.
Misaligned Incentives
Competitive reward models can emphasize high-profile findings rather than complete coverage of the organization’s priorities.
Inconsistent Methods
Different researchers, techniques, and reporting approaches can create uneven results from one test to the next.
