"Sermuno Unified Our Security Operations—and Cut Our Monthly Software Costs"

4.5/5

What do you like best about Sermuno AI?

We are a security company and our people work everywhere: on client sites, in the car, at the office and on night shifts. The biggest win with Sermuno is that everything is the same everywhere. Whether I answer an email on my phone or a colleague does it at the office, we see the same inbox, the same client details, the same schedule and the same status. Nothing lags behind and nothing falls through the cracks. Even small things are solved: our email signature is set up once and follows us on every device, so we no longer fix it per phone or laptop.

Our mail runs on a plain IMAP server and connecting it took minutes, no migration. All shared addresses (control room, planning, administration) sit in one inbox with clear ownership. The AI sorts incoming mail, summarises long threads and has a draft reply ready, so reports that come in outside office hours get picked up much faster. Spam and virus filtering happens before anyone clicks, which for a security firm is a must.

Every client and every site lives in the CRM with contacts, contracts and the full mail history. Notes are the standout for us: per site we keep the instructions, patrol route, opening and closing checklist and the shift handover. A guard types the handover on his phone on location and the office sees it instantly. No more loose papers or chat messages that get lost.

Planning and personnel are the core of our business. Shifts per site, who is where, hours with night and weekend surcharges, and timesheets flow straight into payroll. We get an automatic alert when a guard's security pass or certificate is about to expire, so nobody stands on a site with expired papers. Temporary staff from partner firms are scheduled in the same planning and only see their own shifts through their portal.

A client's email becomes a task in one click, such as a broken camera or an incident report that still needs to be sent. Site visits and client meetings sit in the shared calendar linked to the client. Floor plans, key plans and contracts are stored with the client and open directly on the phone. The night shift uses the team chat with a quick voice or video call when something happens, and an open shift is filled by texting the available guards. Monthly contracts run as recurring invoices, extra shifts and surcharges come from the planning straight into the invoice, and clients pay via the payment link.

As a security company we also look at the security of the tool itself: two-factor login for everyone, permissions per role so a guard only sees his own shifts and sites, and a full audit log of who did what. That is exactly what our clients expect from us.

Then the cost. Before Sermuno we paid around 4,000 euros per month for separate tools for mail, planning, CRM and invoicing. Now we pay around 350 euros per month for the whole office, with every module and much better AI support, which matters a lot these days. That is roughly 3,650 euros per month saved, and everything is easier as well. The team was working in it on day one and support responds fast and actually fixes things.

What do you dislike about Sermuno AI?

Because the platform is still new, we occasionally run into a bug. That is honestly the only thing. On the other hand, there is a dedicated page in the app to report a bug, and what we report there is usually fixed within a few hours, even on weekends. So it has never been a problem for our daily work. Review collected by and hosted on G2.com.

What problems is Sermuno AI solving and how is that benefiting you?

Our biggest problem was fragmentation. Mail, planning, client data, notes and invoicing lived in separate systems that did not talk to each other, each with its own subscription, its own login and its own admin. Information was duplicated or missing altogether, a night-shift handover got lost in a chat group, and people on site saw something different from people at the office.

Staff changes were a job in themselves. For a new hire we had to create an account in four or five systems, set permissions in each one and hand over the mail password. When someone left, you had to go through every system to revoke access, and in practice you always forgot one. For a security company that is not a detail: a former employee who can still reach the schedule, the key arrangements or the mailbox is a risk to our clients.

In Sermuno everything hangs off one account. I invite a new employee once, assign a role, and they immediately see exactly what belongs to that role: their shifts, their sites, the shared mailbox and the instructions. Nobody gets a mail password anymore, because the mailbox is connected once by us and access is granted centrally. When someone leaves, I switch off all their access with one button, from mail to planning to files, and the audit log shows what was done up to that moment.

The work itself now flows in one line. A client's report lands in the shared inbox, is summarised by the AI, becomes a task or a shift in the planning, and the hours and surcharges for that shift end up on the invoice automatically. The guard on site reads the instructions and the handover on his phone, and the office sees what he writes down straight away. Passes and certificates are monitored, so we never have someone on a site with expired papers.

The result: reports are picked up faster, also outside office hours, nothing gets lost between the shift and the office, onboarding and offboarding take minutes instead of an afternoon, and we save around 3,650 euros per month compared to the separate tools. Above all, the peace of mind that everyone looks at the same information and that access is managed in one place is worth a lot for a security company. Review collected by and hosted on G2.com.
