We've run security audits and penetration tests for law firms, healthcare practices, fintech startups, and e-commerce shops across Tampa Bay this year. The same three gaps show up again and again — regardless of industry size or budget.

1. Forgotten admin accounts and default credentials

Nearly every audit turns up at least one admin-level account that was created for a contractor, an old employee, or a "temporary" migration — and never deactivated. Combined with weak or default passwords on network devices (routers, NAS boxes, IoT), this is the single most common entry point we exploit during pentests. Fix: quarterly access reviews, and rotate/disable anything not actively used.

2. No real separation between production and internal networks

A lot of small businesses run customer-facing web apps on the same flat network as internal file shares and POS systems. Once an attacker lands on one, they have a path to everything else. Fix: basic network segmentation (VLANs, firewall rules between zones) closes this fast and is cheaper than most people expect.

3. Unpatched third-party plugins and dependencies

Custom software and websites built on WordPress, common CMS platforms, or older frameworks frequently carry outdated plugins with known CVEs. We routinely find exploitable vulnerabilities that have had public patches available for over a year. Fix: a recurring vulnerability scan (not just a one-time audit) catches this before it becomes a breach.

Why this matters for compliance-adjacent industries

If you're in healthcare, legal, or fintech, these three gaps are also exactly what shows up in HIPAA, PCI-DSS, or SOC 2 gap assessments. Building toward ISO 27001-aligned practices — documented access control, network segmentation, and continuous vulnerability management — solves the security problem and the compliance problem at the same time.

Happy to answer questions on any of these in the comments. We're Zencode I.T Services, based in Tampa, doing penetration testing, security audits, and secure custom software development for businesses here and nationwide (remote).
