Local Contractor Had 48 Cybersecurity Vulnerabilities. A GrYHAT Assessment Found — and Fixed — Every One.
A Southern California contracting business believed their cybersecurity was solid. An on-site assessment told a different story — and the results are a wake-up call for every small business in the region.

SOUTHERN CALIFORNIA — A contracting company operating in Southern California recently underwent a full cybersecurity assessment with GrYHAT Sub Security LLC, a hands-on security firm serving businesses across the region. What started as a precautionary review ended with a finding that surprised everyone involved: 48 distinct, exploitable vulnerabilities spread across the company’s entire digital infrastructure.
All 48 were fully remediated within two weeks.

“We Thought We Were Fine”
The company — whose name is being withheld — came to GrYHAT not because of a breach or an incident. They came because they wanted peace of mind.
They had the basics covered: antivirus software, a firewall, and password-protected systems. In the current threat landscape, that’s where most small businesses stop. For many, that feels like security.
GrYHAT’s assessment revealed what those tools were — and weren’t — protecting against.

What the Assessment Found
GrYHAT conducted an on-site evaluation across five security domains, the same structured methodology the firm applies to every engagement:
Network and Firewall — The firewall in place had not been properly configured for the company’s actual environment. Firmware was out of date, default credentials remained active on network hardware, and inbound ports were open with no documented reason for exposure.
Email Security — The company’s email domain lacked properly configured authentication records (SPF, DKIM, DMARC), leaving it trivially vulnerable to phishing attacks and domain spoofing. This is one of the most common — and preventable — attack vectors in use today.
Endpoint and Device Security — While antivirus was installed, devices on the network were not uniformly managed. Unpatched operating systems and third-party software with known security vulnerabilities were found across multiple machines, including workstations used to handle client contracts and financial data.
Patch Management — Software updates had been regularly deferred or skipped, leaving applications running versions with publicly documented exploits. In some cases, patches addressing critical vulnerabilities had been available for months.
Access Control — Shared login credentials, no multi-factor authentication on key systems, and active accounts belonging to former employees represented some of the most serious risks discovered. Improper access control is among the leading contributors to business data breaches nationally.
Total: 48 vulnerabilities across five domains. All confirmed as exploitable. None theoretical.

Remediation: Hands-On, Not a Report
What distinguishes GrYHAT’s model is what comes after the assessment.
“We don’t hand businesses a list of problems and leave,” said a GrYHAT representative. “We show up, we find it, and we fix it. That’s the whole engagement.”
Over the following two weeks, the GrYHAT team worked through each identified vulnerability — reconfiguring the firewall, updating firmware, securing email authentication protocols, deploying patches, disabling unauthorized accounts, and implementing multi-factor authentication across critical access points.
By the close of the engagement, the contractor’s environment had gone from 48 documented security gaps to zero. Verified.

Why This Matters for Orange County Businesses
Southern California’s contracting industry is a high-value target for cybercriminals. Contractors handle sensitive client data, financial records, subcontractor information, and government-adjacent project documentation. A successful breach can mean lost bids, regulatory exposure, and reputational damage that takes years to recover from.
And yet the pattern GrYHAT encounters is consistent: businesses invest in point products — antivirus here, a firewall there — without ever verifying that those products are properly configured, current, and actually working together.
“The assumption that ‘we have it covered’ is the most dangerous assumption in cybersecurity,” the firm noted.
For OC-based businesses interested in understanding their actual security posture — not their assumed one — GrYHAT offers on-site assessments with full remediation.
