The Risks Chicago Businesses Face Without Professional Cybersecurity
Ransomware & Malware Attacks
Without dedicated cybersecurity defenses, Chicago businesses are vulnerable to malicious software that can encrypt or destroy critical data.
Phishing & Social Engineering Risks
Employees without proper training may fall for phishing emails and scams—compromising your entire network.
Compliance Violations
Failure to comply with HIPAA, PCI, or other industry regulations can lead to legal penalties and reputational damage.
Data Loss & Downtime
Unprotected systems increase the risk of data breaches and extended downtime, costing your business time and money.
Lack of Incident Response Planning
Without a solid response strategy in place, security breaches can escalate quickly—resulting in greater damage and slower recovery.

What Our Clients Are Saying About Our Services
Eric
Services Industry
The best IT provider is the one you never have to see. LeadingIT came out to make corrections to our system on day one and I haven’t seen them since because we don’t need them. They are managing everything behind the scenes and if/when we need them they have the problem fixed immediately….Perfect!

We were not looking for an IT consultant, we were looking for an IT partner. Even better, LeadingIT has become the HPD’s IT “department”. They are a call or click away- at one flat monthly service rate plus cost-effective purchasing power for computers and related equipment.
Mike
Consulting Firm, LeadingIT Client Since 2015
LeadingIT is awesome, they are very knowledgeable and quick to help when we’re having issues or even just need clarification on something. They have a team mentality and aren’t afraid to pull their thoughts together to help deliver exactly what we’re asking for.

We engaged Stephen and his staff over 6 years ago to take over day-to-day IT and help desk management. LeadingIT is a professional organization that takes the hassle out of keeping our workstations updated and network secure. They get the job done each and every time.
Elizabeth
Consulting Firm, LeadingIT Client Since 2015
We are very impressed with the LeadingIT’s service, attention to detail, support, response time and professionalism! Our team is incredibly happy with everything. The system that LeadingIT has to submit issues and questions is super convenient and the follow-up and time to get issues resolved is quick and efficient. I would recommend LeadingIT to everyone.

What a great bunch of people to work with. They are a young motivated, innovative group with the drive to keep our company up to date with the leading edge of technology. Dependable, reliable, and fast problem solvers on many levels. I have had the pleasure to work with Stephen and his crew on a daily basis and have the confidence that whoever answers the call, I will be taken care of in a fast professional manor. Kudos to Stephen and his company.

LeadingIT has helped us identify ongoing security issues and vulnerabilities left by our previous MSP. Through close collaboration, we've been addressing these gaps. While we've made significant progress, this experience has shown that maintaining an active partnership with a pro-active and skilled MSP and following their guidance is crucial to prevent system deterioration.

I just spent half an hour with Bryce, and he was incredibly patient and knowledgeable. He helped me resolve an issue we've been dealing with for months regarding Nicole's computer, discovering that she had been using the wrong calendar entry.
Next, we moved on to my computer, and once again, Bryce proved to be the right person to call. My 70-year-old brain struggled to understand the Authenticator app on my phone for signing into Outlook. After many attempts and with his immense patience, we successfully navigated the two-factor authentication process.
Bryce explained that in the next 5 to 10 years, everything will need to be secured this way. So, when I’m 80 and able to pay my bills or shop online, I’ll be thankful to Bryce for the lesson.
Have a great weekend and tell Bryce, great job.
