A 30-minute review of your email environment and the threats most likely to bypass your current filters.
Email Is Still the #1 Attack Vector
Over 90% of breaches start with email. Generic spam filters miss the targeted attacks that actually cause damage.
Phishing slips past spam filters
Generic spam filtering catches obvious bulk mail. Targeted spear phishing and impersonation attacks pass through unblocked.
Business Email Compromise costs millions
Wire fraud, vendor impersonation, payroll redirection — BEC bypasses spam filters because there’s no malware to detect.
Ransomware comes through email
Most ransomware enters through an email link or attachment. Real-time URL inspection and sandboxing matter more than every other tool combined.
M365 default protection isn’t enough
Microsoft Defender catches obvious threats. Targeted spear phishing and BEC routinely pass through without advanced detection layered on top.
Sensitive client data needs encryption
HIPAA, PCI, attorney-client privilege — sending unencrypted email is a violation, but staff need encryption to be invisible to use.
Quarantine review eats IT time
Without proper tuning, IT spends hours per week reviewing quarantine. Tuned rules plus user self-release fixes this.

Hiring a single in-house IT person costs roughly the same as a full Datastrive managed support agreement — but a single person can’t cover 24/7, can’t be a senior network engineer and a cybersecurity specialist and a vCIO at the same time, and goes on vacation. Managed IT support gives you depth, redundancy, and predictable cost without the recruiting risk.
