Email Security Built Around Real Compliance Requirements

Managed protection, evidence, and response

Phishing Defense
Stop credential theft

Phishing defense helps reduce the risk of credential theft, malicious attachments, spoofed domains, and business email compromise. CSS evaluates your email environment, identifies users and systems that are in scope, and applies controls that fit the way your organization communicates.

The goal is practical protection that supports compliance, not noisy alerts your team cannot manage. Filtering, user training, and monitored response work together to help stop suspicious messages before they become incidents.

Email Encryption
Protect sensitive messages

Email encryption supports secure communication when sensitive data needs to move between clients, patients, vendors, subcontractors, or internal teams. For organizations handling CUI, protected health information, taxpayer data, or financial records, encrypted email can be an important part of the control environment.

CSS helps align encryption with your compliance boundary and user workflows, so protection is deployed where it is actually needed and documented for ongoing readiness.

DLP Controls
Limit data exposure

Data loss prevention helps identify and reduce accidental disclosure of sensitive information through email. CSS can support DLP policies that reflect your operating reality, including regulated records, CUI, client files, patient information, tax data, and financial documents.

DLP works best when it is scoped correctly. CSS starts by identifying what data is in scope, where it flows, and which users need access, helping your organization protect information without unnecessary friction.

Login Auditing
Control account access

Email account compromise often starts with weak access controls or missed login anomalies. CSS supports role-based access control, identity management, MFA alignment, and login auditing to improve visibility into who is accessing mail systems and when.

These controls are especially important for regulated organizations that need to show accountability, monitor privileged users, and support incident review. The result is stronger access discipline and better evidence for compliance programs.

User Training
Train users with purpose

Security awareness and phishing training help users recognize suspicious messages before they click, reply, or transfer funds. CSS focuses training on real risks facing regulated teams, including tax-season phishing, wire fraud, patient data exposure, vendor impersonation, and CUI handling mistakes.

Training is part of a managed workflow, not a one-time checkbox. Reporting and follow-up help reinforce behavior and support continuous security and audit readiness.

Compliance Reporting
Document audit evidence

Email security becomes more valuable when it produces usable compliance evidence. CSS can connect email controls to reporting, policy templates, dashboard visibility, POA&M support, and SSP management where applicable.

This helps your organization show what is protected, who is responsible, what gaps remain, and how remediation is being tracked. For defense contractors and regulated firms, that documentation can be just as important as the technical control itself.
