How cybersecurity is delivered in Connecticut

Our office is at 1 Prospect Park SW in Brooklyn. Engineers schedule visits for work that needs hands, with access and travel agreed for your address. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time, seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work. Confirm landlord access, circuit diversity, cabling and equipment space before approving a network change. Carrier options to check in Connecticut include Frontier Business, Optimum Business and Comcast Business; availability, routing and installation dates must be verified at your address before a failover design is approved.

Who cybersecurity in Connecticut is built for

Businesses we can support in and around Stamford, Greenwich, Norwalk, New Haven and Hartford include financial and investment firms on Salesforce Financial Services Cloud, medical practices and health-system affiliates on Epic, insurance agencies and brokers on Applied Epic, precision manufacturers and aerospace suppliers on Epicor, hedge funds and family offices on Bloomberg Terminal, and law firms on NetDocuments. These are examples of business and application needs, not a list of local clients. We coordinate infrastructure, identity and integration with the application vendor, and identify any compliance requirements during discovery. Companies with an internal IT person can agree a split of responsibilities, systems and coverage hours before work begins.

Continuity planning for your Connecticut business

Start with the systems your team cannot work without. Record the impact of a building power outage, a failed internet circuit, a compromised account and an unavailable application vendor. Then agree recovery priorities, an independent access path, protected backup copies and a test for each critical workflow. Controls reduce particular risks; they do not guarantee that an incident cannot happen.

What is included

Cybersecurity in Connecticut: what NetSys delivers

Watch and respond

  • ThreatDown MDR and EDR on every device, with a 24/7 team that isolates and investigates rather than emails
  • Rapid7 InsightIDR or Microsoft Sentinel collecting identity, email, endpoint and firewall logs so an intrusion is visible in one place
  • Written incident response plan with named owners, tested once a year on a tabletop exercise
  • Post-incident reports written for your insurer and your counsel, not just your IT team

Harden the tenant and the people

  • Microsoft Defender for Business, Entra ID Conditional Access and phishing-resistant sign-in for finance staff
  • Legacy authentication off, dormant accounts closed, forwarding rules and consent grants reviewed monthly
  • Barracuda Email Protection with impersonation protection, plus DMARC enforcement for the domain
  • KnowBe4 training on a recurring schedule, with a wire-transfer and vendor-change verification procedure written for finance

Measure and recover

  • Rapid7 InsightVM scans of the internal and external footprint, with a monthly fix list
  • Managed firewall with intrusion prevention, segmentation and vendor access that is logged and switched off when the work ends
  • Immutable, off-site backups with restores run on a schedule and the result written down
  • Free remote external penetration test before you hire us; Tier 2 source-code testing quoted per codebase
Illustrative engagement

A 30-person medical practice in Hartford

This planning example shows how we could scope the work. It is not a claim about a customer in this market or a measured result. For published customer work, see our case studies.

A 30-person medical practice in Hartford whose Microsoft 365 tenant was set up years ago and never hardened, running Epic and moving money by wire every week. The tenant has five permanent Global Administrators and nobody can say why. Nobody can say whether a mailbox was compromised or the sender was spoofed, the antivirus came bundled with the laptops, and the firewall the last provider installed has a vendor port open that nobody remembers approving.

  • Microsoft 365 investigation: sign-in logs, forwarding rules and consent grants reviewed to establish whether a mailbox was compromised, then multifactor authentication and Entra ID Conditional Access enforced for every account
  • Rapid7 InsightVM deployed for scheduled vulnerability scanning, with the first month's findings prioritized and closed
  • Datto SIRIS backups with immutable cloud copies for the servers and a Microsoft 365 backup for the tenant, with a restore tested and the result written down for the insurer
  • Rapid7 InsightIDR collecting identity, email, endpoint and firewall logs so an intrusion is visible in one console
  • Keeper password management deployed and shared credentials rotated, starting with the ones in the spreadsheet
  • ThreatDown MDR and EDR deployed to every workstation, laptop and server, including the ones partners use from home, with the console monitored 24/7

The insurer's questions get answered with evidence instead of assurances, wire instructions have a verification step that does not depend on memory, and an engineer is watching the tenant at night. The business gets one person to call. The agreement stays month to month.

Published case study

Firewall, antivirus and maintenance for a five-person office

A five-person office needed the basics done properly rather than an enterprise stack. NetSys replaced the internet provider's router with a business-grade firewall configured with sensible rules, secure remote access and logging, deployed managed antivirus on every machine with updates and alerts handled centrally, and put patching, backup checks and health reviews on a schedule. The agreement covers what the office needs and nothing it does not, month to month. No outcome figures were measured for publication.

Compliance in Connecticut: Connecticut’s breach-notification statute and what sits on top of it

Connecticut’s breach-notification statute (Conn. Gen. Stat. § 36a-701b) requires notice of a qualifying breach of personal information to affected residents without unreasonable delay and no later than 60 days after discovery, subject to the statute’s exceptions, and notice to the Attorney General no later than residents are notified. The Connecticut Data Privacy Act adds a duty to use reasonable safeguards for personal data for businesses within its scope, such as those processing the personal data of 35,000 or more consumers or any sensitive data. The service scope should identify the records, access controls, retention settings and incident evidence your business needs; your legal or compliance adviser determines which requirements apply. The security service is built to produce the evidence those rules ask for: multifactor authentication and Conditional Access reports, endpoint detection coverage, vulnerability scan results, backup restore records and a tested incident response plan. Discovery identifies missing records and assigns the documentation work. Applicable duties depend on the business, data, exemptions and contracts; your legal or compliance adviser determines which requirements apply.

What cybersecurity costs in Connecticut

Cybersecurity is priced per user per month when it runs as an ongoing service, and per project for an assessment or a remediation. What moves the number: how many devices and identities are in scope, how much incident remediation and recovery is needed beyond the monitoring and authorized MDR actions in scope, which compliance standard the evidence has to satisfy, and whether the Microsoft 365 tenant is already on Business Premium or the security tooling comes from us. The free external penetration test costs nothing and runs remotely before any of that. Our managed IT pricing page explains how the fee is built.

How the monthly fee is built

Who this fits, and who it does not

Best fit: businesses with enough people, money movement or regulated data that a breach would hurt, and no security team of their own: professional practices, healthcare groups, importers, financial firms, nonprofits and agencies holding client credentials. Companies with an internal IT person fit as a co-managed arrangement.

Not a fit: organizations that want a security product installed and left alone. The service is monitored, reviewed and reported monthly, and it changes the way administrators, finance staff and vendors work. If that is not wanted, a tool purchase serves better than an engagement.

Common Questions

Cybersecurity in Connecticut: FAQs

What is managed detection and response, and do we need it?

MDR puts an EDR agent on every device and a 24/7 team behind it that isolates a compromised machine and investigates, rather than an antivirus that quarantines a file and moves on. Cyber insurers now ask for it by name, which is the practical reason most businesses in Connecticut end up with it.

Can you work alongside our internal IT person?

Yes. In a co-managed arrangement your person keeps the day-to-day and we run monitoring, the security stack, vulnerability management and after-hours response, with the split written into the agreement.

Do we need a security assessment before signing up?

The free external test is where most engagements start. A fuller assessment of the tenant, devices, network and backups is scoped separately and produces a prioritized fix list that becomes the first ninety days of the service.

Do you have an office in Connecticut?

How can IT support help with Connecticut data-security requirements?

Connecticut’s breach-notification statute (Conn. Gen. Stat. § 36a-701b) requires notice of a qualifying breach of personal information to affected residents without unreasonable delay and no later than 60 days after discovery, subject to the statute’s exceptions, and notice to the Attorney General no later than residents are notified. The Connecticut Data Privacy Act adds a duty to use reasonable safeguards for personal data for businesses within its scope, such as those processing the personal data of 35,000 or more consumers or any sensitive data. NetSys can help document the relevant systems, controls and incident evidence within an agreed scope; legal notification decisions remain with your authorized business and legal team.

Start with the free test

See what an attacker sees before they do.

The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. Internal reviews and ongoing security management are scoped separately.
