Managed Security Services —
Westchester, NY
Cybersecurity is not a product you buy once — it's an ongoing practice of monitoring, response, and adaptation. Corstar delivers managed security services that actively protect Westchester businesses from evolving threats, 24/7.
Why Point-in-Time Security Tools Aren't Enough
Buying an antivirus program in 2026 is like buying a smoke detector for a building that has already caught fire. Modern threats are active, adaptive, and specifically designed to evade point-in-time security tools. You need ongoing monitoring and response — not just protection software.
Managed Security Services — What's Included
Our managed security stack covers every major attack surface for a Westchester small or mid-size business — endpoints, email, network perimeter, identity, and data.
Managed EDR
Endpoint Detection and Response (EDR) replaces traditional antivirus with behavior-based threat detection that catches sophisticated malware, ransomware, and fileless attacks that signature-based tools miss.
Email Security
Advanced anti-phishing, anti-spam, and business email compromise (BEC) protection. Safe Links rewrites URLs in real time. Safe Attachments detonates suspicious files before they reach your inbox.
Managed Firewall
Next-generation firewall management — rules, policies, threat signatures, and firmware — actively managed and updated rather than configured once and forgotten.
Identity & Access
Multi-factor authentication deployment, conditional access policies, privileged account management, and dark web monitoring for compromised credentials across your organization.
DNS Filtering
Block malicious domains, command-and-control servers, and inappropriate content at the DNS layer — before any malicious content reaches your devices.
Incident Response
When a security event occurs, our team responds — contain the threat, preserve evidence, remediate affected systems, and restore normal operations as quickly as possible.
Security Awareness Training — Your People Are the Perimeter
No technical control stops a trained employee from clicking a phishing link. And no firewall prevents an employee from giving their password to someone posing as IT support.
Corstar's managed security services include ongoing employee security awareness training — simulated phishing campaigns, targeted education, and quarterly reporting on your organization's security culture.
Employees who have completed security awareness training are dramatically less likely to fall for phishing attacks. We make training ongoing and relevant — not a one-time checkbox.
Security Awareness Program Includes
- Simulated phishing campaigns — realistic, not punishing
- Targeted training modules for employees who click
- Quarterly reporting on click rates and improvement over time
- Dark web monitoring — we alert you when employee credentials appear in breach databases
- Security policy acknowledgment tracking
- Executive reporting on security culture metrics
Managed Security for Compliance
- HIPAA technical safeguards implementation
- NY DFS Cybersecurity Regulation (23 NYCRR 500) controls
- SOC 2 security control implementation
- Cyber insurance requirement documentation
- Annual security risk assessments
- Audit logging and evidence collection
Managed Security That Satisfies Regulators and Insurers
HIPAA, the NY DFS Cybersecurity Regulation, and cyber insurance underwriters all require documented, ongoing security controls — not a one-time security assessment. Our managed security services produce the logs, reports, and documentation that compliance audits and insurance applications require.
If you're applying for or renewing cyber insurance, ask us about our compliance documentation package. See our data compliance services →
