Healthcare Cybersecurity
Healthcare Cybersecurity & Managed Threat Protection
Healthcare-focused cybersecurity for medical practices: from Microsoft 365 hardening and AI-powered email security to 24/7 threat monitoring and zero-trust access, layered, enterprise-grade protection for your patient data, your people, and your practice.
Defense in depth, not a single tool
Modern attackers exploit identity, email, and cloud misconfigurations far more than firewalls. We layer protection so attackers face barriers at every step.
Defense in depth
Email, endpoint, identity, and monitoring layered together, no single point of failure.
AI-powered detection
Behavioral analysis flags anomalies in real time, catching attacks signature tools miss.
Human + technology
Automated defense plus ongoing awareness training to address the #1 vector: human error.
Our complete security stack
Every layer covered, from the inbox to the dark web, backed by 24/7 expert support.
Microsoft 365 / Google hardening
DKIM, DMARC & SPF, MFA enforcement, conditional access, admin least-privilege, and audit logging.
Advanced AI email security
Blocks phishing, business-email-compromise, and zero-day threats with AI behavioral analysis & sandboxing.
Endpoint protection (EDR)
Next-gen detection & response with ransomware rollback, automated isolation, and threat hunting.
Zero-trust privilege access
Application whitelisting, just-in-time admin access, least-privilege, and credential vaulting.
Patch management & RMM
Automated OS & third-party patching with remote monitoring, closing the window attackers exploit.
Dark web monitoring
Continuous scanning for your compromised credentials & data, with automated password-reset triggers.
Security awareness training
Interactive training and simulated phishing that turns employees into your first line of defense.
Helpdesk & alert triage
Round-the-clock analysts who know your environment, fast escalation and monthly health reports.
Compliance & policy
Audit-ready documentation and control mapping for HIPAA, PCI DSS, SOC 2, CMMC, and NIST CSF.
Who we protect
Enterprise-grade protection without the enterprise-size security team.
How we deploy your security program
A structured onboarding that gets you protected fast, without disrupting your business.
Cybersecurity questions
What does the managed program include?
M365/Google hardening (DKIM/DMARC/SPF/MFA), AI email security, EDR endpoint protection, zero-trust access, patch management, 24/7 monitoring, awareness training, dark web monitoring, and audit-ready policy documentation, all managed by our team.
How quickly can you deploy?
Most deployments complete in 2-4 weeks. We prioritize the highest-risk areas first, typically email security and MFA, so you're protected from day one.
Do you support Microsoft 365 and Google Workspace?
Both. We harden authentication, enforce MFA, configure conditional access, and secure sharing on either platform.
What compliance frameworks do you help with?
HIPAA, PCI DSS, SOC 2, CMMC, GDPR, and NIST CSF, with technical controls and audit-ready documentation.
