Common Issues Naperville Businesses Encounter Without Cybersecurity Experts
Ransomware & Malware Attacks
Without layered cybersecurity defenses, Naperville businesses face a growing risk of malware infections that can lock, steal, or damage essential data.
Phishing & Social Engineering Risks
Untrained staff may unknowingly click malicious links or reveal credentials, giving cybercriminals access to your systems.
Compliance Violations
Failure to meet regulatory requirements like HIPAA, PCI-DSS, or CMMC can result in fines, failed audits, and reputational damage.
Data Loss & Downtime
Lack of secure backups or incident response planning increases the risk of prolonged downtime and permanent data loss after an attack.
No Incident Response Plan
Without a clear security roadmap, businesses may struggle to respond quickly or effectively when a breach occurs—leading to deeper consequences.

What Our Clients Are Saying About Our Services
Eric

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.

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.

My computer locked up with a warning that Trojan viruses were on the loose. I emailed LeadingIT with my phone and received a call from Alex soon after. Alex was calm, explained what was going on, and was able to both resolve the issue and assure me that no damage had been done. From start to finish, the process moved much more quickly than I had expected.

Dustin Looper worked tirelessly to help set up my Macbook so that I could access my company's H: drive through SMB connection. He followed up to confirm all data within the shared drive is accessible.

Hissan from LeadingIT helped me fix a problem that had been going on for at least two months and could not be solved by any of the partners I work with, which includes a company worth $15 billion dollars. He was quick to respond to my ticket, walked me through everything to identify the problem, and jumped into a meeting with the partners to help with problem solving. He researched the problem between our first contact and the meeting and found the solution to the issue in about one workday. I appreciate Hissan and LeadingIT for the speedy solution.
