Attackers don't keep business hours. Neither do we.
Sergeyko Security is your fully managed security team — detecting, containing and stopping ransomware, phishing and account takeover across every device and identity.
- No long setup projects
- Works with your IT team
- Insurance-ready controls
Off-hours attacks
Most ransomware is launched overnight or on weekends, when no one is watching.
Stolen identities
Compromised credentials are the most common way attackers get in.
Antivirus isn't enough
Modern attacks use legitimate tools. You need humans who hunt and respond.
What we do
Layered protection, fully managed.
Every layer attackers target — devices, identities, cloud and people — covered by one team accountable for the outcome.
24/7 Managed Detection & Response
Human threat hunters watch your environment around the clock, investigate every alert and contain attackers before they spread — nights, weekends and holidays included.
Next-Gen Endpoint Protection
AI-driven, behavior-based protection on every laptop and server. Ransomware is stopped, isolated and rolled back — often before a user notices.
Active Response & Containment
When something gets in, we don't just send you a ticket. We isolate hosts, kill sessions and lock accounts in real time, then walk you through recovery.
Microsoft 365 Identity Protection
We detect account takeover, session hijacking, impossible travel and malicious inbox rules across your cloud tenant — and shut them down fast.
Zero Trust Access Policies
Sign-ins are evaluated by location, device health and risk. Unmanaged devices and suspicious countries are blocked or challenged automatically.
Multi-Factor Authentication
Frictionless push and biometric MFA for email, VPN, cloud apps and servers — rolled out, enforced and supported by us.
Security Awareness Training
Bite-sized training and realistic phishing simulations that turn employees into your first line of defense.
Compliance & vCISO
Policies, risk reviews and evidence for HIPAA, PCI, CMMC, SOC 2 and cyber-insurance questionnaires — without hiring a full-time CISO.
