Cybersecurity Services That Protect NJ & NYC Small Businesses
One phishing email can lock your files, drain a bank account, or expose your clients' data. Setnom builds layered defenses around your business (and watches them 24/7) so a bad click doesn't become a business-ending event.
Attackers Don't Pick Targets Anymore. Their Software Does.
Modern attacks are automated and indiscriminate, bots scan every business on the internet for weak spots. Small NJ businesses get hit precisely because attackers expect no real defenses. These are the four ways it usually happens.
Phishing Emails
A convincing fake (a DocuSign request, a Microsoft login page, an "overdue invoice") tricks one employee into handing over credentials. It's the front door for nearly every attack that follows.
Ransomware
Malware encrypts every file you have (contracts, patient records, accounting data) and demands payment to unlock them. Without protected backups, you're choosing between paying criminals and starting over.
Business Email Compromise
An attacker quietly takes over a real email account, watches your invoices for weeks, then sends "updated wire instructions" to a customer or your bookkeeper. The money is usually unrecoverable.
Weak & Reused Passwords
One password reused between a breached website and your business email gives an attacker everything. Without multi-factor authentication, a stolen password is a master key.
Unpatched Systems
Every skipped Windows update leaves a documented, publicly known hole in your network. Automated attack tools check for those exact holes, and find them within days of disclosure.
Nobody Watching
The average intrusion goes undetected for weeks. Without monitoring, an attacker has all the time they need to map your network, find your data, and pick the worst possible moment to strike.
No Single Tool Stops Modern Attacks. Layers Do.
Antivirus alone hasn't been enough for a decade. Real protection means stacking defenses so that when one layer misses (and eventually, one will) the next layer catches it. A phishing email that slips past the filter meets MFA. Malware that lands on a laptop meets EDR. And everything meets a monitored, locked-down network.
This is the stack we deploy and manage for businesses across New Jersey and New York City. It's enterprise-grade protection, sized and priced for a small business, and if we already run your IT through our managed IT services, it integrates directly into the same support and reporting you already get.
- Endpoint Detection & Response (EDR) Smart protection on every computer that spots attack behavior (not just known viruses) and isolates the machine automatically.
- Multi-Factor Authentication (MFA) A stolen password becomes useless without the second factor. Deployed on email, Microsoft 365, and every critical account.
- Email Filtering & Phishing Protection Malicious attachments, spoofed senders, and credential-harvesting links are stripped out before they reach an inbox.
- Network Lockdown Tools Hardened firewalls, segmented Wi-Fi, and closed ports, so guests, smart devices, and intruders can't reach business systems.
- 24/7 Security Monitoring Alerts from every layer flow to us day and night, so suspicious activity gets investigated in minutes, not discovered weeks later.
The Layers Most Providers Skip: People, Patches & Proof
Tools alone don't make you secure. The defenses below close the gaps that software can't, and they're built into how we work.
Employee Security Awareness
Short, practical training plus simulated phishing campaigns turn your staff from the easiest target into your first line of defense. Whoever clicks the test email gets coaching, not a real breach.
Patch Management as a Security Control
Most successful attacks exploit vulnerabilities with patches already available. We treat patching as a security discipline, tested, scheduled, and verified across every device, not left to chance.
Backups as the Final Safety Net
When everything else fails, verified backups decide whether ransomware is a bad afternoon or a closed business. Our cloud backup & disaster recovery service keeps protected, tested copies attackers can't encrypt.
Cyber Insurance Readiness: Get Covered, Stay Covered
Cyber insurance has quietly become a security audit. Carriers now refuse to write (or renew) policies for businesses that can't prove they have multi-factor authentication, endpoint detection and response, and tested backups in place. Worse, answering a questionnaire wrong can void your coverage exactly when you need it: claims get denied every year because a business checked "yes" on MFA that was never actually enabled everywhere.
We solve this in three steps. First, we implement the controls carriers require. Second, we document them (what's deployed, where, and how it's verified) so the proof exists before anyone asks. Third, we sit with you (or your broker) and help complete the insurance questionnaire accurately, in plain English, line by line. NJ businesses we work with walk into renewals with evidence instead of guesses, which often means better premiums too.
When Something Gets Through: Incident Response
No honest provider promises zero incidents. What matters is what happens in the first hour. When an alert fires, we isolate the affected machine before anything spreads, investigate how the attacker got in, and restore clean data from verified backups. Compromised email accounts get locked, passwords rotated, and sessions revoked, critical for stopping wire-fraud attempts in progress. Once you're operating again, we close the hole that let the attacker in, and your Microsoft 365 environment gets re-hardened so the same trick doesn't work twice.
For local businesses, proximity matters in a crisis. We serve companies from Paramus and Hackensack to Newark, Jersey City, and Manhattan, close enough to be on-site the same day when an incident demands hands-on work. Check our NJ & NYC service areas, and if a machine needs hands-on cleanup or rebuilding afterward, our computer repair & help desk team handles it.
Where to Start
Most owners don't need a lecture about threats, they need a straight answer to one question: "How exposed are we right now?" That's what the free assessment answers. We review your email security, passwords and MFA coverage, endpoint protection, network configuration, and backups, then hand you a prioritized list of gaps. Fix them with us, fix them with someone else, but know where you stand. If your security questions are part of a bigger technology decision, like moving to the cloud or supporting remote work securely, our IT consulting service ties it all together. Book your free IT assessment and get the straight answer.
Our Incident Response, Step by Step
Protected clients rarely get here, EDR and monitoring stop most attacks early. But when something does get through, this is exactly what we do.
Contain
Infected machines are isolated from the network immediately and compromised accounts are locked, stopping the attack from spreading while we work.
Investigate
We determine how the attacker got in, what they touched, and whether data was taken, facts you'll need for insurance, clients, and any reporting duties.
Recover
Systems are cleaned or rebuilt and your data is restored from verified backups, prioritized so the parts of the business that earn money come back first.
Harden
We close the vulnerability that caused the incident, strengthen the surrounding layers, and brief you in plain English on what changed and why.
