Buying more cybersecurity tools does not automatically make an organization safer, and smaller organizations are not too small to attract attackers. Unit 42 consultants identify three recurring misconceptions from customer casework: that a bigger tool stack guarantees better protection, that organization size provides safety, and that governance, risk and compliance (GRC) controls are merely audit paperwork. Their practical message is to build an integrated defense, assume compromise is possible, and make sure controls are owned and tested.
Unit 42 says its article draws on interviews with three consultants about misconceptions they encountered in customer casework. The observations are qualitative, not a measured estimate of how common these problems are across organizations. In particular, the article gives no case count, percentage, observation period or sampling method for its statement that “in a majority of the cases observed” organizations had not properly implemented, used and enforced tools they already had.

Myth 1: More security tools always mean better protection
Adding a specialized product for every emerging threat can create a larger, harder-to-operate stack without closing the gaps that matter. Unit 42 warns that tools deployed without a unified strategy can create operational vulnerabilities instead of stronger defense.
Why tool accumulation can backfire
- Alert fatigue: Poorly tuned tools can produce false positives and make important alerts harder to distinguish.
- Unused capabilities: An organization may already own useful functions in its current platforms but fail to configure or use them.
- Operational overhead: Each tool adds work for the people responsible for operating it and responding to its output.
- Visibility gaps: Integrations can leave teams without a clear view across the security environment.
Start with an inventory, not another purchase
- Inventory the tools already deployed and review their documentation and available capabilities.
- Classify tools by security domain so the team can see what each is meant to protect or detect.
- Review the security architecture, including how tools connect and where their visibility ends.
- Identify overlapping functions, underused features, tuning problems and integration gaps.
- Consolidate overlap where it makes sense, then tune the remaining portfolio to the organization’s needs.
The objective is not simply to reduce the tool count. Unit 42’s consultants put it this way: “The goal is not simply to reduce tools but to build a security portfolio that is streamlined, integrated and capable of providing effective coverage.”

Myth 2: Smaller organizations are safe from attackers
Organization size does not make an organization immune from compromise. Unit 42 consultants say smaller organizations can be targeted as a way into larger, better-protected entities. They point to smaller public agencies with connections or access to larger organizations and critical infrastructure as an example of why an organization can matter to an attacker beyond its own size.
The consultants also say that in a majority of the cases they observed, organizations had not properly implemented, used and enforced tools they already possessed. That is a casework observation—not a population-wide statistic—and the article does not provide a case count or percentage.
Plan for exposure, not presumed insignificance
Unit 42 recommends an assume-breach posture: plan as though a compromise could occur, rather than relying on the belief that attackers will overlook a smaller organization. A grounded security strategy should account for risks including unpatched software, social engineering and supply-chain vulnerabilities.
As the Unit 42 consultants state, “An organization’s size, industry or current security practices do not make it immune from being compromised.”
Myth 3: Security controls and GRC are just compliance checkboxes
Controls can reduce risk only when they are implemented and operated effectively. Treating governance, risk and compliance as audit paperwork can leave practical threats unaddressed, even if a control is documented.
How a neglected access review can create an attack path
Unit 42 uses periodic privileged-access reviews as an example. If reviews are neglected, accounts can retain excessive permissions. If an account is compromised, those permissions can help an attacker escalate privileges or move laterally through the environment.
Make the risk controls matrix operational
Unit 42 recommends treating GRC as active threat mitigation, choosing a recognized framework and managing a risk controls matrix (RCM) with clear operational detail. Its suggested elements include:

- Clean mapping between applications and data.
- Schedules for testing controls.
- Checks that controls work as intended, rather than merely appearing in documentation.
The article names NIST SP 800-53, CIS Controls v8 and ISO 27001 as framework examples; it does not compare or rank them. The relevant practical question is whether the organization’s chosen controls address its risks and are actually maintained and verified.

Each misconception substitutes an easy proxy for real security: the number of tools, the size of the organization, or the existence of compliance paperwork. Unit 42’s advice instead emphasizes architecture reviews, recurring assessment and an accurate picture of the organization’s security posture. As its consultants put it, “Effective organizational security is built on foundational discipline, not on chasing industry trends and continually shifting to the next solution.”
