    What Happened

    A 25-person CPA firm was targeted by a sophisticated ransomware attack in mid-March. Our endpoint protection isolated the threat in seconds, preventing any data loss or downtime during their busiest month.

    Where It Went Wrong

    Traditional antivirus would have missed the behavioral signals of this new ransomware strain. Without active monitoring, the initial intrusion would have spread firm-wide before being detected.

    How Red Door Shield Stops This

    Keep what's valuable secure

    Active endpoint detection and response (EDR) identified and killed the malicious process before it could encrypt a single file.

    Inspect what's coming in

    Our 24/7 security team received an immediate alert and verified the threat was contained within minutes.

    Trust through validation

    Verified backups were already in place and tested, providing the ultimate safety net if containment had failed.

    The Takeaway

    Zero downtime, zero data lost. The firm continued working through tax season without a single client's data being exposed.

    ACCOUNTING FIRM

    When Tax Season Becomes Open Season

    In April 2024, Legacy Professionals LLP, an accounting firm based in Westchester, Illinois, just outside Chicago, was breached by the LockBit 3.0 ransomware group. Over two days, the attackers moved through the firm’s network and quietly copied files before anyone noticed. Those files held names, Social Security numbers, driver’s license numbers, and medical and health insurance details for 216,752 people. That August, the criminals published the stolen data on the dark web. The firm did not finish notifying affected individuals until early 2025, and it now faces class-action lawsuits over the breach and the delay.

    PROPERTY MANAGEMENT

    38 Gigabytes of Tenant Trust, Gone in a Day

    In December 2024, Tri County Property Management, based in Sandwich, Illinois, was breached, with attackers removing roughly 38 gigabytes of data from its systems. Property managers sit on exactly what criminals want: tenant Social Security numbers, bank account and payment records, lease files, and applicant background data. The same pattern played out at Income Property Management, where a single intrusion exposed driver’s licenses, Social Security numbers, dates of birth, medical details, and even passport numbers, and the firm did not notify affected people until more than a year later.
