LanGuard. Watches every hour. Reports every morning.

Illustrative hourly check. Figures from the manufacturer's November 2026 reports.
Security built for big IT teams doesn't fit small businesses
Per-seat costs add up
Traditional tools charge for every user, every month. The bill grows whether or not the risk does.
Alert fatigue
Dashboards produce hundreds of alerts. Most are harmless, so the real ones get missed.
Small IT teams
Often one person looks after everything. They need clear answers, not another console.
What LanGuard watches
Microsoft 365 identity watch
Hourly review of sign-ins, failed logins, mail sent from unfamiliar connections, inbox rule and forwarding changes, app consents and impossible-travel patterns.
Firewall and network watch
Gateway status, both internet lines, intrusion prevention mode, blocked attacks, devices online, firmware and admin logins.
Secure remote access watch
Who connected, from where and for how long, plus any failed or unusual logins outside normal patterns.
Plain-English daily report
One email each morning around 08:00: all clear, or items to review with a recommended action for each. Urgent problems alert straight away.
Tested checks first. AI where it earns its place.
Scripted checks gather and count the data the same way every hour; AI interprets what is unusual. Every finding is dismissed or escalated with the reason written down, so your team can check the thinking instead of reading raw logs.
Real-world example
A week with LanGuard at a UK manufacturer
Figures from five daily reports in November 2026. Addresses, account names, device names and system details are withheld: a security report is a map of a network.

Escalated to a person
- Monitoring gap. Overnight the firewall vendor's service stopped allowing log access. An alert went out at once, every hourly check confirmed it, and the morning report gave the exact fix.
- Mail from an unfamiliar connection. One mailbox sent a single message from outside the office. Low priority, but flagged: confirm the user was working remotely, otherwise reset the password.
- Exposed service. Repeated probing of one internet-facing system. Advice: limit who can reach it, or put it behind the VPN.
Dismissed, with the reason given
- 41 failed sign-ins. All from the office network; pattern consistent with mistyped passwords.
- Mail sent from home and mobile. Matched to UK broadband, mobile providers or known VPN addresses. Normal remote working.
- Wi-Fi channel changes. An access point detected radar and moved channel. Normal behaviour.
