UNIT 42 consultants have highlighted three common cybersecurity misconceptions drawn from their observations of customer environments. The first is that adding more security products automatically improves protection. They say poorly integrated tools can instead create alert fatigue, false positives, underused features, higher costs and visibility gaps. AI-powered telemetry may reduce the workload, but treating it as a “black box” can make alerts harder for analysts to understand.
Unit 42 recommends auditing existing products, reviewing the security architecture by function, and consolidating and tuning overlapping platforms before buying new ones.
The second myth is that small and medium-sized organisations are unlikely to be targeted. According to the consultants, attackers may compromise smaller organisations as a route into larger, better-protected businesses; this is particularly relevant to smaller public-sector agencies connected to major organisations or critical infrastructure.
Unit 42 also says many organisations fail to implement or enforce the tools they already own, and recommends an “assume breach” approach alongside a properly resourced security strategy.
The third myth is that security controls and governance, risk and compliance (GRC) processes are merely compliance exercises. Unit 42 warns that neglected controls, such as privileged-access reviews, can leave accounts with excessive permissions and give attackers a route to lateral movement and privilege escalation.
It recommends treating GRC as active risk reduction, adopting a framework such as NIST SP 800-53, CIS Controls v8 or ISO 27001, and maintaining a risk controls matrix with named owners, accurate application mappings, scheduled testing and checks that controls work as intended.
