Hire the Best Wireless Security Specialists

I am a cybersecurity and IT infrastructure professional with experience in security operations, cloud security, firewall engineering, VPNs, endpoint protection, vulnerability management, and managed IT support. I help businesses secure their networks, troubleshoot infrastructure issues, improve threat detection, harden cloud environments, and build practical security programs. My experience includes Palo Alto, Cisco ASA, Zscaler, CrowdStrike, Splunk, Microsoft Defender, Rapid7, Tenable/Nessus, AWS, Azure, GCP, Fortinet, and SonicWall. I can help with cybersecurity assessments, firewall/VPN troubleshooting, vulnerability remediation, cloud security reviews, endpoint security, SIEM tuning, incident response support, and small business IT support. My focus is simple: reduce risk, improve reliability, and deliver clear technical results without unnecessary complexity.

I'm the Level III IT consultant who works for other MSPs and IT consultancies — the senior hand you bring in for the hard problems junior techs escalate: network redesigns, cybersecurity hardening, server migrations, and emergency triage. 30+ years in the trenches, U.S. Navy trained, Top Rated with a 100% Job Success score. Based in the Chicago area / Northwest Indiana, with remote and on-site coverage nationwide. Where I go deep: - Networking & Security: Design, configure, and secure networks with SonicWall, Fortinet, Cisco/Meraki, UniFi/Ubiquiti, TP-Link Omada, and Netgear — firewalls, VLANs, VPNs, 2FA/MFA, site-to-site bridges. - Servers & Hosting: Nearly 30 years of cPanel/WHM, DNS, POP3/IMAP, Microsoft 365, and Google Workspace; Apache/PHP/MySQL on RHEL/CentOS/AlmaLinux for reliable hosting and maximum uptime. - Systems & Cloud: Windows Server 2025, Windows 11, Linux, and macOS; Azure/Hyper-V virtualization and AWS/GCP deployments — from design through deployment and ongoing operations. - Microsoft Stack: Microsoft 365 administration and migration, Entra, Intune, and Active Directory Group Policy. Industry experience: HIPAA-compliant IT for medical/dental, Dealer Management Systems for automotive groups, secure corporate networks, and structured wiring and access control for warehouses. How I work: Precise and methodical. Project-based engagements first, hourly for smaller targeted work. I bring clear status updates and a bias toward documenting what I change, so the next person — internal or external — can pick up where I left off. I coordinate across internal IT teams, third-party vendors, and contract boards when an engagement requires it. Background: Self-taught IT professional since 1997; U.S. Navy Aircrewman, Patrol Squadron 26 (VP-26), 1990–1995, earning a Navy Achievement Medal for technical expertise on a classified surveillance system. Network Operations Center engineer at eSignal/Interactive Data, 2000–2007. Founded Ateki LLC in 2002. If you need a senior consultant who can redesign a network, harden security, migrate a server room, or own the escalations your team is stuck on — and who shows up, communicates, and documents — let's talk about your project.
