An accounting firm doesn’t sell software or servers. It sells trust and punctuality: the filing is correct, and it’s on time. That’s exactly why IT is such a sensitive spot. The entire service hangs on an accounting package, a document server and a mail environment, and the deadlines are written into law. An outage in a quiet week is annoying. The same outage in VAT filing week is a problem your clients feel.
The risk profile of an accounting firm
Look at an accounting firm through an attacker’s eyes for a moment and three things converge. Financial data of dozens to hundreds of companies in one place. An organisation too small for its own IT department. And a hard dependency on deadlines, which makes the willingness to pay during a ransomware incident painfully predictable. It’s no coincidence that accounting firms keep showing up in incident reports at home and abroad.
Then there’s a second kind of pressure, and it comes not from attackers but from clients. Larger companies fall under NIS2, and that law obliges them to vet their suppliers too. An accounting firm with access to such a client’s financial systems is a supplier in the most sensitive category there is. The questionnaire is coming. The only question is when.
What monitoring concretely solves
Monitoring turns “we believe everything is running” into a measured fact. For a firm, that means the following in practice.
The systems the firm runs on are watched continuously: the accounting package, the file server, the mail, the connection to government portals. When something falters, you know within minutes, not when the first file manager gets stuck at nine o’clock. During peak periods that difference is worth gold: a problem detected on Monday night is fixed Tuesday morning before anyone noticed.
Disk space, backup jobs and certificates get watched in the boring, quiet way that prevents big incidents. A backup that has failed three nights in a row is precisely the kind of detail nobody notices until it really matters.
And everything is recorded. Availability per system, detected incidents, response times. When that NIS2 questionnaire arrives, or when your professional liability insurer asks about your IT security, you have reports instead of promises.
”But we already have an IT provider?”
Most firms have a party managing their servers and workstations, and that’s fine. But management and monitoring are two different things. The provider installs, patches and resolves tickets after someone calls. Monitoring is what makes the ticket exist before the client calls, and what keeps an independent log of what happened when. In practice the two work excellently side by side: your IT provider fixes, the monitoring sees and documents.
Starting small is allowed
A firm of five to fifty people doesn’t need an enterprise rollout. Map the critical systems, put detection on them, tune the alerts properly and add a monthly report: that’s the core in place. Through Althona I set that up with CheckMK and run it continuously, so the trust you sell to clients is something you can extend to your own systems too.
