Managed SOC stops an active intrusion
Challenge:
At 4:10 a.m. on Christmas morning, an attacker gained a foothold on a server and immediately tried to blind the defenses, issuing a command to disable the Windows firewall across all profiles (MITRE ATT&CK T1562.004, defense evasion). On an unmonitored network it would have gone unnoticed until real damage was done.
Solution:
Our managed SOC detected the firewall-disable command the moment it executed, correlated related suspicious activity into a single incident, and escalated to remediation in minutes. The compromised host and its virtualization host were isolated, cleaned, and rebuilt from a known-good state.
Results:
- Intrusion contained the same business day, before spread or exfiltration
- No ransomware event, no data loss
- Attack neutralized while still in its opening move

Managed EDR finds a threat hiding in plain sight
Challenge:
On an endpoint onboarded during a client business acquisition, malicious Windows services had been installed under names designed to blend in, masquerading as legitimate 'Microsoft Security' system services. Traditional antivirus had not flagged them, and telemetry indicated they predated the security tooling entirely.
Solution:
Our managed endpoint detection and response platform identified the disguised services as malicious and automatically isolated the affected machine from the rest of the network, cutting off any path for the infection to spread while analysts investigated. The endpoint was remediated and returned to service clean.
Results:
- Host quarantined within seconds of detection
- Zero spread to other machines, servers, or backups
- Second, lower-severity incident on the same client handled the same way
Disguised malware detected and the host auto-isolated, zero spread to other systems.Discuss Your Project
Independent penetration testing for a financial firm
Challenge:
A financial-advisory practice handles exactly the kind of sensitive client data that regulators and clients expect to be protected. 'We think we're secure' isn't good enough in that world. They needed independent, third-party proof that their defenses held up under real attack conditions, across their network and their Microsoft 365 tenant.
Solution:
We coordinated a full third-party engagement: an external network penetration test, an internal network vulnerability assessment, and a dedicated cloud security assessment of their Microsoft 365 tenant. Findings fed directly into a hardening and virtualization-platform deployment to close the gaps identified.
Results:
- External, internal, and cloud penetration tests completed
- Documented assessment to show clients, partners, and insurers
- Remediated environment with hardening deployed

Backup recovery when it mattered
Challenge:
A staff accountant logged in one morning to find critical folders had vanished from a shared drive, years of downloaded bank statements and financial records across multiple subfolders, simply gone. Without a working backup, that's lost data and a frantic scramble.
Solution:
Because the client was on our managed backup service, the missing data was already protected. The team located the folders in a recent server backup and restored them intact, files, subfolders, and structure, within an hour of the request.
Results:
- Every file restored exactly where it belonged
- No re-downloading statements, no gaps in financial records
- Restore completed within one business day
Business-critical financial records fully restored from backup within one business day.Discuss Your Project
