Encryption is essential — but it’s not enough

For many organizations, email encryption feels like the final step in protecting sensitive communication. It checks the compliance box, offers peace of mind, and reassures clients that their data is secure.

But here’s the truth: encryption only protects what it sees. And most email-based threats don’t come from intercepted messages — they come from the inside.

Most threats never touch encryption

Phishing, spoofing, business email compromise — these attacks don’t need to break encryption. They bypass it entirely by targeting people, not data. Once an attacker has access to an inbox, encrypted or not, your information is exposed.

Encryption helps protect data in transit, but not necessarily at rest or in context. If a legitimate user is tricked into sharing credentials, clicking a link, or wiring funds, encryption doesn’t stop the damage.

Compliance mandates it — but risk goes further

Regulations like HIPAA, GDPR, and FINRA require secure transmission of sensitive information, especially for client data, medical records, or financial reports. Encryption meets that requirement. But compliance frameworks are often a floor — not a ceiling.

They rarely account for:

  • Account takeover via MFA fatigue or phishing

  • Insider misuse or negligent forwarding

  • Advanced persistent threats that wait inside a mailbox

Real protection starts with threat visibility and response, not just message scrambling.

Encryption is still a must — just not the whole story

Used correctly, encryption is a critical part of a modern security strategy. It’s especially important for regulated communication, legal disclosures, client reports, and sensitive healthcare or financial data.

But it has to work alongside other protections:

  • Threat detection and prevention

  • Account access controls

  • Backup and archiving

  • Human oversight and response

Encryption is a seatbelt — not a crash avoidance system. It minimizes damage but doesn’t stop the collision.
