Managed Cybersecurity Services for New York City — SentinelOne, AI Governance, Regulatory Compliance

Why cybersecurity is non-negotiable for NYC regulated firms

Financial services (RIAs, trading firms, fintech), legal practices, and healthcare are targets. FINRA rules 3210 and 4530 mandate system validation and cybersecurity oversight. SEC cybersecurity disclosure rules require firms to report material incidents. HIPAA enforcement has accelerated, and NY DFS imposes breach-response timelines (72 hours for notification). A single ransomware infection or data breach can trigger regulatory fines, client litigation, and loss of license. Cybersecurity isn't an IT cost; it's a business imperative.

We operationalize cybersecurity as managed service. You get endpoint detection and response (EDR), email security, threat intelligence, and compliance reporting — without building a dedicated security team in-house. Your named engineer (see /services/managed-it/) monitors security signals 24/7, investigates alerts, and coordinates incident response aligned to regulatory timelines.

Endpoint detection and response via SentinelOne

Every laptop, desktop, and server in your environment runs SentinelOne Singularity agent. This agent monitors process behavior, file system activity, and network communications in real-time, looking for indicators of compromise. SentinelOne detects fileless malware, lateral movement, privilege escalation, and data exfiltration that traditional antivirus misses. When a threat is detected, the agent can isolate the endpoint (disconnect from network) in seconds, preserving evidence and preventing spread while your engineer investigates.

We configure SentinelOne with rules tailored to your business. Legal practices using legal-tech platforms get different detection rules than trading firms using Bloomberg terminals. We baseline normal behavior and tune alerts to reduce false positives so your engineer focuses on real threats. If an endpoint is compromised, you get immediate notification and a forensic report showing how the attacker got in and what they accessed.

Email security and backup via Barracuda

Email is the attack vector. Phishing, business email compromise (BEC), and malware-laden attachments arrive daily. Barracuda filters inbound mail against known malware signatures, suspicious URLs, and impersonation patterns. Outbound email is scanned to prevent accidental data exfiltration (a partner's tax return sent to the wrong domain, for example). We also configure Barracuda backup to replicate every email message to off-site storage, so if ransomware encrypts your mailbox server, you recover from the backup copy.

For HIPAA and FINRA firms, email retention policies are non-negotiable. Barracuda enforces retention rules (FINRA requires 6 years of communications for supervisory records) and provides audit logs showing who accessed which emails and when. Regulatory auditors see this data and confirm compliance.

AI governance as a security and compliance pillar

ChatGPT, Claude, and other LLMs are now standard in many firms. Employees use them to draft emails, analyze documents, and write code. But unmanaged AI use creates risk: a lawyer pastes a confidential contract into ChatGPT, and the LLM vendor trains on that data. A financial analyst feeds proprietary trading strategies to an AI chatbot. FINRA and SEC have flagged AI governance as a control requirement, and NY DFS is drafting explicit AI governance rules.

We help you formalize AI governance. This includes employee acceptable-use policy (what AI tools are approved, what data can and cannot be used), vendor risk assessment (evaluating LLM providers for data handling and SOC 2 compliance), and technical controls (blocking unapproved AI sites via firewall, enabling audit logging for approved tools). We also provide AI training for senior staff and board-level briefings on AI risk and opportunity.

Threat intelligence and incident response playbooks

We subscribe to threat feeds (malware hashes, command-and-control domains, IP addresses used by known threat actors) and correlate them against your environment. If a user's workstation connects to a known malicious domain, we flag and investigate immediately. We also maintain incident-response playbooks tailored to your industry: ransomware response for law firms, fraud detection for RIAs, data-breach notification for healthcare. When a real incident occurs, your team knows exactly what to do and in what sequence.

Compliance documentation and board reporting

Regulators want evidence: audit logs, penetration test reports, vulnerability assessments, and breach-response timelines. We maintain a compliance dashboard showing your current security posture (patch levels, EDR detection rates, email security block statistics). This dashboard feeds quarterly board reports and regulatory filings. FINRA examiners see that your firm is logging, monitoring, and responding to incidents. SEC examiners see your cybersecurity-risk oversight structure. HIPAA auditors see your business-associate agreement and your breach-notification readiness.

How cybersecurity integrates with managed IT

Cybersecurity is not separate from IT operations; it's embedded. Your named engineer (managed IT) monitors both performance and security signals from the same dashboard. A slow server and a malware detection get the same triage process. Patch management includes security patches prioritized by threat level. User provisioning includes security baselines. When you call your helpdesk for a password reset, the engineer also checks for anomalous login activity from that user's account. See /services/managed-it/ for details on how managed IT and managed cybersecurity work together.
