Founder story

Sentilio started as an internal tool for my own tech agency, FilioTech. I manage hosting for some clients, while others host elsewhere, but either way I wanted a much clearer view of whether their websites were actually healthy and secure. That used to mean checking different tools and browser tabs for SSL, DNS, email configuration, uptime, domain renewals, WordPress plugins, themes and everything else around the site. Then there are the things that change unexpectedly. Someone edits DNS, a certificate fails to renew, a site does not come back properly after a reboot, or a vulnerable plugin appears. As the technical partner, I wanted to know before the client did. So I started automating the checks, adding monitoring, alerts and reporting, and bringing everything into one place. That gradually became Sentilio. I launched it publicly on my 40th birthday as my first SaaS product, although I still use it every day across the sites I manage. Now I am hoping other agencies, freelancers and business owners who look after websites will find it as useful as I do.

FAQ

Who is Sentilio for?

Sentilio is for agencies, freelancers and business owners who look after one website or many. It also suits IT providers and hosting companies that manage websites for others. Agencies can choose an Agency plan to monitor client websites continuously. Freelancers and businesses can buy credits and run scans whenever they need them, with no subscription.

What do I get when I start free?

New accounts receive 10 free credits, enough for 3 full scans. You do not need a payment card. Each scan gives the website an A+ to F grade, a list of findings with recommended next steps and a PDF report you can download.

Do I need to install anything?

No. A standard scan runs from the outside, so there is nothing to install and you do not share any server logins. You only connect a website if you want to manage its WordPress updates, which is part of Pro monitoring on Agency plans. The app guides you through that step.

What is the difference between a scan and monitoring?

A scan checks a website at one moment and gives it a grade. You can run scans when you need them or set up scheduled scans, and both are paid for with credits. Pro monitoring, available on Agency plans, keeps watching a website between scans. It checks uptime about every three minutes, alerts you to DNS changes and known WordPress vulnerabilities, and runs a full scan every day.

Can I use Sentilio with websites that are not WordPress?

Yes. Scans work on any website, whatever it is built on. Checks such as SSL, DNS, email authentication and security headers apply to every website. Platform checks depend on the technology Sentilio detects. WordPress update management applies only to connected WordPress websites.

Does Sentilio protect my website from attacks?

No. Sentilio detects and reports. It finds configuration issues, known vulnerabilities in supported software, unexpected changes and downtime, then tells you what to look at first. It does not block attacks, and it does not replace a firewall, backups or a penetration test. A good grade shows that the checks passed. It is not a guarantee that a website is secure.

Can I send reports to clients?

Yes. Every completed scan produces a PDF report you can download or email from Sentilio. The first PDF and the first emailed report from each scan are included. Extra copies use 1 credit each. Agency plans add white label reports, so clients see your brand rather than ours.

Can I use it without a subscription?

Yes. Buy credits when you need them and use them on any number of websites. £5 buys 50 credits. A full scan uses 3 credits, and a scheduled scan uses 6 credits including the emailed report. An Agency plan is a separate subscription for continuous monitoring.

How many websites can I add?

As many as you like. Credits work across any number of websites. On an Agency plan, your Pro seats set how many websites have continuous monitoring at the same time: 10, 25, 50 or 100. You can move a seat from one website to another whenever you need to.

How much does a Sentilio website security scan cost?

A full scan uses 3 credits, which is £0.30. Credits cost £5 for 50. A scheduled scan uses 6 credits a run (£0.60) and includes the emailed PDF report.

Hey 👋 It actually started as an internal tool for my own company. I look after a mix of my own sites and client sites, and I was constantly jumping between different tools for SSL, DNS, headers, email configuration and uptime. Each tool answered one question, but I wanted one place that could check everything, give me a simple grade, and tell me what needed attention first. So I built Sentilio for myself first, used it internally for a while, and then realised other agencies and businesses managing multiple sites probably had the same problem. I launched it publicly at the end of August on my 40th birthday, so now I am at the slightly harder stage... finding the first paying customers 😅
