Security for the way offices get attacked

Most break-ins at offices like yours start with a convincing email or a reused password. We put practical controls in place to stop them, and real people watch for what slips past.

What the numbers say about Georgia

Georgians filed 25,936 complaints with the FBI's Internet Crime Complaint Center (IC3) in 2025, putting the state 10th nationally by count. Those victims reported roughly $534.6 million in losses, the 9th highest total of any state. Across the country, IC3 tallied 24,768 business email compromise complaints in 2025, with reported losses topping $3 billion. Only investment fraud cost victims more.

Business email compromise is simple and effective. Someone breaks into a real mailbox or fakes a lookalike, then asks for a payment to go somewhere new. The invoice looks right. The tone sounds right. The money goes to an account that is emptied within hours.

Why Peachtree Corners offices are exposed

The businesses in ZIP 30092 lean toward the kinds criminals like. Census data for 2023 lists 182 insurance agencies and brokerages, 78 computer systems design firms and dozens of engineering, accounting and law offices. They share a few traits:

  • Money moves by email. Agencies handle premiums and claim payments. Professional firms send and pay invoices all day. A changed bank detail is easy to miss.
  • Valuable data. Policyholder records, Social Security numbers, client contracts, source code and drawings all have resale or ransom value.
  • Trusted access to others. IT and software firms often hold credentials into their own clients' systems. A breach at a small firm can become a breach at a much bigger one.
  • Hybrid staff. People sign in from home, the office and client sites, so sign-in security matters more than the office firewall alone.

Layers we add

  • Multifactor authentication for Microsoft 365, VPN or remote desktop, and all admin logins, using phone app prompts that take a second to approve.
  • Conditional access that blocks risky sign-ins, such as logins from unexpected countries or unmanaged devices, and shuts off old sign-in methods attackers abuse.
  • Email filtering for phishing, spoofed domains and malicious attachments, plus a report button in Outlook so staff can flag a suspicious message in one click.
  • Endpoint detection and response installed on each PC, Mac and server. Rather than relying on a list of known threats, it flags suspicious behavior and can quarantine a device that starts encrypting files.
  • Human alert triage: an engineer looks at each security alert and takes action. Nothing piles up unread.
  • Least privilege: everyday accounts carry no admin rights, leavers lose access on their last day, and shared logins go into a password manager.
  • Network separation so guest Wi-Fi, conference room gear and cameras can't reach your file shares or finance systems.
  • Training and phishing tests: short lessons and realistic test emails so staff learn what a fake invoice or login page looks like.
A rule worth writing down: before changing where money goes, call the requester on a number from your own records. Never trust the number printed in the email.

If something gets through

If an attacker grabs a mailbox or malware lands on a laptop, speed matters. We lock the account or pull the device off the network, trace what was opened, hunt for hidden forwarding rules and other footholds, and rebuild from known-good copies. Then we work through notifications with you, whether that means the insurer, the bank, clients or regulators. Having a written incident plan before that day makes the response faster and calmer.

Insurance, carriers and contracts

Cyber insurance applications now ask pointed questions about MFA, endpoint detection, backups and admin access. Larger clients and carriers send security questionnaires of their own. We help you answer them accurately and fix the items that would cost you a policy or a contract. Engineering and software firms doing work for the Department of Defense may also face CMMC requirements, and we can help you scope what applies.

First steps

Our security review covers tenant configuration, recent sign-ins, endpoint protection, the firewall, backups and the list of admin accounts. The findings fit on a few pages, written for a manager and sorted by risk. Quick wins like universal MFA and shutting off legacy sign-ins are usually done within a fortnight. From then on, alerts get daily attention, accounts get a monthly audit and every quarterly meeting includes a security update.

Questions about cybersecurity

We're a small agency. Are we really a target?

Yes. Most attacks are automated and aimed at anyone with email and money moving through it. Small offices are often chosen because their defenses are thinner, not because anyone singled them out.

Can you help with a cyber insurance application?

Yes. We go through the questions with you, answer the technical ones accurately and close gaps such as missing MFA or untested backups before renewal.
