Computer security service is the search of an organisation that thinks in machines: the desktops in the office, the laptops in the van, the computer that runs the books, and someone to keep them safe. The term predates the cloud and the modern market answers it with newer vocabulary, endpoint protection, managed devices, patching cadence, but the need it describes is concrete and has a concrete shape: every machine protected, updated, backed up and recoverable, with a person to call. That shape is narrower than a full security programme and cheaper, and buyers searching this term are frequently right about their own scope: a machine-centred organisation needs machine-centred protection first. This guide honours the term: what protecting the computers actually involves now, what it costs per machine using licensed list prices, and the point at which machine-thinking stops being enough, which arrives with the first emailed payment instruction.
What protecting the machines involves now
Per machine, the modern floor is five controls: a current endpoint protection agent, the successor to desktop antivirus, watching what runs; operating system and application patches applied on a cadence measured in days; a local account discipline, named users, no shared logins, administrator rights only where work requires; encryption switched on, so a stolen machine is a hardware loss rather than a data loss; and backup of what the machine holds, restore-tested. All five are per-machine facts a service can deploy, verify and report, which is what makes the machine-centred scope honestly buyable: coverage is countable, and the monthly report can say every machine, patched, protected, backed up, and be checked.
What it costs per machine
The tooling floor is public: endpoint protection lists at prices like CrowdStrike Falcon Go at $59.99 per device billed annually, and per-user suites like Microsoft Defender for Business at $3.00 per user per month paid yearly cover the person's machines together. A service fee stacks deployment, watching, patching and the phone call on top, per device or per user monthly. Overpaying happens in two ways: paying per device for a fleet that shrank, the annual re-count is your job, and paying service fees on tooling you already license, which the quote should credit. The managed pricing guides on this site walk both arithmetic traps in detail.
Where machine-thinking stops
Machines can be perfectly protected while the organisation loses badly, because money moves on instructions and instructions arrive in mailboxes. The emailed supplier-detail change, the boss-fraud transfer request, the credential harvested on a real-looking page: none of these touch the endpoint agent. The moment the organisation notices this, the scope widens from computers to conduct, and the controls are written ones: a payment confirmation procedure, a credential rule, an access policy with a leaver's step. The free sheet on this site counts that written set from your facts and prices the drafting at your own hourly figure, so the machine service you buy sits inside a programme rather than substituting for one.
Questions people ask about computer security service
What does a computer security service include?
Per machine: endpoint protection deployed and watched, patching on a stated cadence, account discipline (named users, minimal admin rights), encryption on, and restore-tested backup, with monthly per-machine reporting. Countable coverage is the point.
How much does computer security cost per machine?
Tooling lists at prices like $59.99 per device per year (CrowdStrike Falcon Go) or $3.00 per user per month (Microsoft Defender for Business) on the licensed pages cited here; service fees stack watching and patching on top, per device or user monthly. Credit tooling you already own.
Is protecting the computers enough?
No: fraud arrives in mailboxes and moves money without touching a protected machine. The machine service needs a written companion, payment confirmation, credential rules, access policy, which the free sheet counts into your set.
