Three Cyber Risks Quietly Bleeding Sub-$100M Companies

Companies under $100M in revenue sit in the most exposed seat in the cyber economy. Large enough to be worth attacking, small enough to lack the staff, tooling, and governance maturity the threat now demands. Three risks dominate, and the typical response misreads each one.

The first is third-party and MSP exposure. Mid-market firms outsource IT to keep headcount lean, Datto RMM here, Meraki there, a fractional CISO somewhere, handing persistent privileged access to organizations they cannot meaningfully audit. When the MSP gets compromised, the blast radius is every client. Kaseya was not an anomaly. The fix is not a SOC 2 PDF on file. It is SOC 2 Type II reviewed annually, vendor-specific access reviews, segmented admin tiers, and phishing-resistant MFA enforced on the MSP side before they touch your environment.

The second is identity collapse. MFA coverage is partial, offboarding lags by weeks, contractors run on personal devices outside any MDM, and five admin accounts authenticate everything. Attackers no longer break in, they log in. The fix touches HR, legal, and operations, not just IT: same-day deprovisioning, conditional access, BYOD policy with technical enforcement, quarterly entitlement reviews, and phishing-resistant MFA on every privileged path. Push-notification MFA is no longer adequate.

The third is the human attack surface. Annual compliance-checkbox awareness training produces nothing. Meanwhile employees paste customer data into consumer AI tools, click invoice-themed phishing, and approve wire changes by email. PEBKAC is not a punchline, it is the dominant vector. The fix is continuous and consequence-based: simulated phishing tied to manager dashboards, sanctioned AI tooling with DLP, callback verification on every payment instruction change, and tabletops that include the CFO and the board.

None of these require a security engineering team. They require ownership, governance, and willingness to disrupt convenient practices. The companies that survive the next five years will be the ones that stop treating cyber as IT’s problem and start treating it as a board-level operating risk.
