Who We Protect
Cybersecurity for Chicago Businesses Without a Security Team
Virdual IT is the cybersecurity partner Chicago businesses call when they want to know what is going on inside their systems. Hoping nothing goes wrong is not a plan.
Most small business breaches do not start with a movie-style hack. They start with a forgotten legacy login, a mailbox rule nobody reviewed, a laptop without protection, or a stolen password that still works. Offices along Ogden Avenue in La Grange and the I-88 corridor in Oak Brook rarely have anyone watching for that cyber risk. Since October 2019, Virdual IT has delivered proactive, Chicago cybersecurity services that find those risks, close them, and keep watching.
What’s Included
What Virdual IT Cybersecurity Services Include
These are the cybersecurity services Chicago small businesses need most. Virdual IT security services cover the places a cyberattack actually gets in, with layered defenses under one flat monthly plan.
- Microsoft 365 security reviews and login monitoring
- Legacy protocol removal, so a stolen password cannot skip MFA
- Email security hardening against phishing and spoofing
- Managed device protection against malware and cyber attacks
- Device compliance policies, including remote workers
- Identity and access management with multi-factor sign-in
- Firewall management for network security, plus dark web monitoring for stolen credentials
- Monitoring that runs around the clock, with threat detection on logins and devices
Microsoft 365
Microsoft 365 Security Audits
A Virdual IT Microsoft 365 security review shows who can reach your accounts and whether someone is already inside.
It looks at your setup the way an attacker would. Virdual IT flags logins from unusual places and looks for accounts with more access than the job needs. It hunts for mailbox rules that quietly forward mail to outsiders, and for old accounts nobody turned off. Since the platform is cloud computing reached from anywhere, the review also finds legacy protocols. Those old login methods let a stolen password slip past MFA. Each finding is written up in plain English, then fixed and monitored with the right tools.
Email Security
Email Security and Phishing Protection
Virdual IT hardens email for Chicago businesses, because a single bad message can lead to a stolen login or a rerouted invoice.
Mail flow rules and inbound connectors are where these attacks hide. Each one gets reviewed by Virdual IT, and anything that should not be there comes out. Domain records then stop criminals from sending mail as you. Anti-phishing filters and safe-link checks sit on top, and monitoring flags a hijacked mailbox before it reaches your clients.
Endpoints
Endpoint Protection and Ransomware Defense
Virdual IT replaces basic antivirus with managed endpoint protection that stops ransomware and other cyber threats as they run.
Traditional antivirus waits to recognize a known threat. Modern protection, built on platforms like SentinelOne and Bitdefender EDR, watches what a program does and shuts down an attack in progress. It runs on every laptop and desktop Virdual IT manages, even at home. Compliance policies decide which devices may reach sensitive company data. Passwords live in Keeper Security’s password manager, not on sticky notes, and software stays patched.
Compliance
Compliance Support for HIPAA, PCI, and Cyber Insurance
Virdual IT helps regulated Chicago businesses with regulatory compliance for HIPAA, PCI DSS, and cyber insurance, using controls that hold up under scrutiny.
For dental and health care offices, that means access controls, encryption, and the written policies a HIPAA review asks for. Restaurants and markets need a payment network built for PCI. Law firms need client files locked down to protect information privacy. Insurers now commonly ask about MFA, device protection, and backup testing. With Virdual IT, local businesses can answer those questions honestly instead of guessing.
Incident Response
How Virdual IT Handles a Security Incident
Virdual IT aims to catch an attack at its first warning sign and stop it before it spreads across your Chicago operations.
- Detect: monitoring flags the warning sign, often before anyone on your staff notices.
- Contain: the affected account or device is isolated so the problem cannot spread.
- Recover: systems come back from protected backups, with downtime kept as low as possible.
- Close the gap: Virdual IT explains what happened in plain English and fixes the weakness that let it in.
Incident response comes from the same team that set up your security. Nobody is learning your network mid-crisis.
How to Choose
How to Choose a Cybersecurity Company in Chicago
The right choice among cybersecurity companies in Chicago is the one that tests the real entry points and explains each risk in words you understand.
- Will they secure your email platform, not just install antivirus?
- Who watches for threats, and who responds when something is found?
- Are the engineers US-based, and do they already know your systems?
- Is security priced flat, or sold through fear-based upsells?
- Can they document what a regulator or insurer will ask for?
Virdual IT’s answers: the assessment covers Microsoft 365 and email, not just antivirus. A team of real US engineers who already know your environment watches and responds. Billing is flat, and Virdual IT never recommends technology or cybersecurity solutions you do not need.
What Chicagoland Businesses Say About Virdual IT
I had an excellent experience working with Denny Kuruklis/Virdual IT. He was incredibly knowledgeable, efficient, and immediately identified the sources of several computer and email issues I had been struggling with. He quickly got everything sorted out, including making sure my Microsoft account, Office apps, Outlook, OneDrive, and email were properly configured across my computers. He also provided helpful advice about account security and future computer purchases. I really appreciated how quickly and thoroughly he got everything working—and how clearly he explained things along the way. Highly recommend!

We’re extremely happy with the work and would definitely recommend Denny and Virdual IT to anyone needing cameras, wiring, or IT work.

Denny is awesome! He is always quick and efficient when helping with all of our networking needs. He can resolve anything I throw at him and is very knowledgeable. Definitely recommend!!
Not only are they supremely knowledgeable with computers, but Denny hooked up my printer with my computer in 5 minutes when I tried for hours before. Thank goodness.
Denny is an outstanding, young man who is not only capable of providing an excellent service, but very much in tune with his customer's concerns. I am absolutely impressed with his work ethic.
Denny and his team at Virdual IT are great people. I was having trouble with my internet connection, my phone provider and my security system. I called Denny and he took care of everything. Him and his team are very professional. I know if something were to go wrong, I can call Denny and he'll answer right away... no answering machines or waiting hours to get a call back. I have been using Virdual IT since February, and things have never gone soother with my phone system, cameras and internet. Mr Greek Gyros will forever be a client of Virdual. Thanks.
I was looking to setup a home security system and I was close to just hiring someone from ADT to hook it up. However, Denny informed me about how I would be paying monthly fees forever, and that these cameras weren't even worth that much. He setup 8 cameras for me which I can access through my phone remotely. It was a one time fee and I don't have to worry about ADT's monthly fees anymore! Thank you Denny!
Brought Virdual my laptop because its running slow. i had virdual upgrade the hard drive and ram and now it performs faster so now i don't need to buy a new laptop. Extremely professional
Virtual is a great company they do excellent work and are always on top of their game. You need to give them a try. They did my website and it is phenomenal! Be sure to hit up Denny!
Fantastic experience! I had Virdual install internet access points at multiple locations at my business. Prompt service, great prices, very responsive, and customer support is an A+. Will only be using Virdual for my IT needs in the future.

I have Virdual do all of my computer related work at home and for my business. There are countless amounts of issues I encountered setting up my own internet router & modem at home along with my own computer builds.
Virdual is super professional and responsive, all problems are solved within the first day. Denny, the owner, is extremely polite and knowledgeable. Highly recommend to anyone!
Virdual has set me and my business up with many computers and has done several jobs for me outside of computer repairs. These are your go-to guys for low voltage electrical and computer/office problems and setup. Extremely professional and have the knowledge to get the job done right.

Cybersecurity FAQs for Chicago Businesses
How do I know if our Microsoft 365 has already been compromised?
Often you cannot tell without a security review. Attackers who get in usually stay quiet, setting up forwarding rules or waiting for a wire transfer to intercept. Virdual IT inspects logins and mailbox rules for Chicago businesses, fixes what it finds, and keeps monitoring.
Is antivirus enough to protect my business?
No. Traditional antivirus only catches threats it already recognizes, and modern attacks change to avoid that. Managed protection from Virdual IT stops malicious software by watching what it does. Compliance policies then hold each Chicago office laptop to the same standard.
What does a cybersecurity audit include?
This risk assessment from Virdual IT checks logins and permissions, mailbox rules, legacy protocols, domain records, device coverage, and MFA. Each finding comes with a plain-English explanation of the risk and the fix. You get a clear list of each vulnerability, ranked by what matters first.
Can you help us meet cyber insurance requirements?
Yes. Insurers commonly ask about MFA, device protection, and backups. Virdual IT puts those controls in place for Chicagoland businesses and documents them, so the application answers are accurate.
We are a medical office. Can you help with HIPAA?
Yes. Virdual IT builds access controls, encryption, and written policies into the systems of dental and health care offices across Chicagoland. Then the team keeps them current. That ongoing attention is what a HIPAA review looks for.
What happens if we get attacked?
Virdual IT monitoring is built to catch an attack at its first warning sign. If an incident happens, the Virdual IT team that secured your Chicago business contains it, restores systems from protected backups, and closes the gap that let it in.
How much do cybersecurity services cost for a small business in Chicago?
It depends on the number of users and devices and your compliance needs. Cybersecurity is part of the Virdual IT flat monthly rate, so nobody upsells you on fear. The free IT assessment gives your Chicago business a real number for your environment.
How is cybersecurity as a service different from managed IT?
Managed IT keeps your systems running day to day. Cybersecurity as a service, or managed cybersecurity, focuses on keeping attackers out: assessments, hardening, device protection, and monitoring for threats. As a managed service provider, Virdual IT delivers both as one set of managed services, so security is never a separate vendor.
Are our systems watched after hours?
Yes. Virdual IT monitoring runs around the clock and flags suspicious logins as they happen. Support hours are Monday to Friday, 7:00 AM to 5:00 PM, and Saturday 8:00 AM to 3:00 PM. After hours, the team stays reachable when critical systems in Chicagoland are at risk.
Is your security team based in the US?
Yes. Every engineer who secures your accounts or protects your devices works in the US on the Virdual IT team. No overseas contractors touch your company data.
