Cybersecurity Stack for a 1,000-Employee Professional Services Firm

Recommendation: An EDR platform bundled with a managed detection and response (MDR) service, rather than a standalone EDR the in-house team monitors themselves.

Why it fits this profile: A 2-person team cannot staff 24/7 alert triage on top of everything else they own. MDR shifts the always-on monitoring burden to the vendor while the in-house team retains decision authority on response. Buying EDR alone at this team size usually means alerts pile up unread.

Recommendation: A cloud identity provider enforcing SSO and phishing-resistant MFA across all business applications, with conditional access policies for anomalous logins.

Why it fits this profile: At 1,000 employees, credential-based attacks (not zero-days) are the most likely path in. This is the highest-leverage, lowest-cost control available — it closes the most common attack path for the smallest ongoing operational cost of anything on this list.

Recommendation: A dedicated email security layer on top of the mailbox provider's built-in filtering — targeting business email compromise and invoice-fraud style attacks specifically.

Why it fits this profile: Professional services firms are disproportionately targeted by BEC because of routine wire transfers and client correspondence. Native mailbox filtering catches commodity spam and malware; it is not tuned for the impersonation and financial-fraud patterns this industry actually sees.

Recommendation: A lightweight, continuous external + internal vulnerability scanning service, reviewed monthly rather than a heavyweight enterprise platform requiring dedicated headcount to operate.

Why it fits this profile: A 2-person team can realistically review and act on a monthly cadence. A platform that assumes a dedicated vulnerability management analyst will go unused — the tool has to fit the team size that exists, not the team size the vendor assumes.

Recommendation: Short, frequent phishing simulations and micro-training (monthly, 5 minutes) rather than an annual compliance-driven training module.

Why it fits this profile: Given BEC is the realistic top threat here, staff need to recognize social-engineering patterns specifically, and that skill decays fast. A once-a-year training satisfies a checkbox but does not change Tuesday-afternoon behavior.

Recommendation: Immutable, offsite backups with a tested recovery runbook — validated by an actual restore test at least twice a year, not just backup-job-succeeded monitoring.

Why it fits this profile: At this size, a ransomware event is an existential risk without a lean security team able to respond to a live incident. The recovery capability substitutes for the incident-response depth a bigger organization would have in-house.
