Website Security Monitoring

European website security monitoring: file-integrity, malware, uptime and blacklist alerts watched by engineers. From EUR120/month. 24/7 response, NDA.

Manual, expert-ledEvidence-based findingsFree remediation retest

Website security monitoring is what turns a breach from a week-long disaster you discover through an angry customer into an alert you act on within the hour. SafetyBis watches sites for businesses across Europe around the clock, tracking file changes, malware, uptime, blacklisting and newly disclosed vulnerabilities, so problems are caught while they are still small.

Most site owners find out they were hacked days or weeks after the fact, usually from Google, a customer, or their host suspending the account. By then the damage is done: data gone, reputation dented, ranking dropped. Monitoring exists to close that gap between compromise and discovery, which is where nearly all the real cost of an incident actually lives.

What website security monitoring covers

Monitoring is not a single tool. It is a set of continuous checks against a known-good baseline of your site, backed by people who read the alerts and act on the ones that matter. The point is early warning: catching the file that changed at 3am, the admin account nobody created, the plugin that just went from safe to vulnerable overnight.

Malware and blacklist scanning, including hidden SEO-spam injections
Uptime and defacement checks so an outage is not a surprise
Alerts on new admin users and unexpected privilege changes
Vulnerability tracking of your CMS, plugins and libraries
TLS certificate and DNS monitoring to catch expiry and hijacking

Web security monitoring only earns its cost if someone acts on what it finds. A dashboard full of unread alerts protects nobody, which is why our plans put a human between the alert and you.

What we actually monitor

Site security monitoring spreads across several layers, because an attacker can show up in any of them. Here is what each check is really watching for.

File integrity

We fingerprint your web root and compare it continuously. When a file changes, appears or disappears without a corresponding deployment, that is a strong early signal of a compromise, and it usually shows up long before any visible symptom.

Malware and reputation

Regular scanning looks for injected code, malicious redirects and the hidden spam pages that only render for search engines. In parallel we check whether your domain has appeared on Google Safe Browsing or vendor blacklists, so you hear it from us and not from a drop in traffic.

Vulnerability and patch status

We track the versions of your CMS core, plugins, themes and key libraries against known-vulnerability feeds. The moment a component you run picks up a serious advisory, you get told, because that window between disclosure and patch is when automated attackers strike.

Why version tracking matters

In the majority of the compromises we later clean up, the entry point was a component with a known, published vulnerability that simply had not been updated. Monitoring the patch status of what you run turns that from a silent risk into a prompt to act.

Availability and configuration drift

Uptime checks catch outages and defacement quickly. Certificate monitoring warns you before TLS expires and breaks the site or trust in it. DNS monitoring flags unexpected record changes, which can be the first sign of a domain hijack or a redirect attack.

How our monitoring works

Internet security monitoring is only as good as the process behind the alerts. Ours is built to cut noise and surface the few things that genuinely need you.

Establishing a baseline

We start by capturing what “normal” looks like for your site: its files, its users, its traffic shape, its certificates. Everything after that is measured against this baseline, which is what lets us tell a routine deployment apart from an intrusion.

Alerting and triage

Raw alerts are triaged by an engineer before they reach you. A plugin update you made is not an incident; the same file changing at midnight from an unknown source is. This filtering is the difference between alerts you trust and alerts you learn to ignore.

Escalation and response

When something looks like a real compromise, it goes straight to our 24/7 incident response team, who can contain it and begin cleanup rather than just emailing you a warning. Detection without a response plan only tells you how bad it got.

Why continuous monitoring beats a periodic scan

A once-a-quarter security scan or an annual test is valuable, but it is a snapshot. Your site changes every time you publish, update a plugin, or ship a feature, and an attacker does not wait for your next scheduled review.

Continuous monitoring closes the gap between those snapshots. If a plugin you rely on is found vulnerable the day after your annual test, a periodic model leaves you exposed for a year; monitoring flags it that day. The same goes for website security testing done at launch: it proves the site was sound then, not that it still is after six months of changes. Monitoring is what keeps the assurance current. The two are complementary, not competing: a test tells you the site is sound today, and monitoring tells you the moment that stops being true.

Monitoring paired with incident response

Detection and response belong together. An alert that nobody can act on out of hours is a missed opportunity dressed up as diligence.

The handover is instant

Because the same team monitors and responds, there is no cold handover to a stranger when something happens. The people who know your site’s baseline are the ones who contain the incident, which shaves hours off the response.

Retainer-style cover

For sites where downtime is expensive, monitoring plus a response commitment works like a retainer: the watching is continuous and the reaction is pre-agreed, so a 2am compromise gets handled at 2am, not at the start of the next business day. For an online shop or a booking platform, the hours saved usually pay for the plan many times over in a single incident.

Monitoring and compliance

Continuous monitoring is not just good practice; several frameworks expect it, and being able to show it satisfies auditors.

Logging and detection controls

ISO 27001 Annex A covers event logging and monitoring, and PCI DSS requires both logging and file-integrity monitoring for systems in scope, under requirements 10 and 11.5. Our monitoring records and reports are structured to evidence those controls.

Demonstrating diligence for GDPR

GDPR expects appropriate technical measures to protect personal data and to detect breaches promptly, since notification timelines start when you become aware. Monitoring is a large part of being able to say when awareness began, and to show you were watching.

What you get

You get more than a stream of raw alerts. The service is packaged so you can see it working and hand the output to whoever asks.

What monitoring catches that owners miss

The value is easiest to see in the situations that play out on unmonitored sites, where the same problems run for weeks before anyone notices. Here are three that come up again and again.

The slow SEO-spam infection

A site gets injected with hidden pages that only render for search-engine crawlers, so the owner browsing normally sees nothing wrong. Ranking slides for months, blamed on an algorithm change, until traffic collapses. File-integrity monitoring flags the injected files on day one, before Google ever indexes the spam.

The forgotten vulnerable plugin

A plugin that was fine at launch picks up a critical advisory a few months later. On an unwatched site nobody connects the dots, and it becomes the entry point for a compromise. Version tracking turns that advisory into an alert the day it lands, so you update before the automated exploitation reaches you.

The expired certificate

Less dramatic but surprisingly common: a TLS certificate lapses, browsers throw warnings, and conversions drop until someone notices. Certificate monitoring warns you well before expiry, so it never becomes a visible outage in the first place.

The quiet new admin

An attacker who gets a foothold often creates a fresh administrator account to keep access even after a password change. That account can sit unused for weeks, waiting. Alerting on new privileged users surfaces it immediately, while it is still just a warning and not yet a breach.

Pricing

Website security monitoring is billed as a monthly plan, tiered by how many sites you run and how fast you need us to respond when something trips. Here is the shape of the plans.

FAQ

How much does website security monitoring cost?
Plans start from €120 per month for a single site, rising to €250 and up for business-critical sites with 24/7 response included. Security monitoring cost scales with the number of sites and how fast you need us to react. You get a fixed quote after a free call.
How is this different from a security plugin’s built-in scan?
A plugin scan runs on your site and emails whoever set it up, if anyone reads it. Our monitoring adds engineer triage, continuous file-integrity and vulnerability tracking, and a response team that acts, rather than a dashboard you have to watch yourself.
What happens when the monitoring detects something?
Real threats are escalated to our 24/7 incident response team, who contain the issue and begin cleanup, not just send a warning. Routine changes are filtered out during triage so you only hear about what matters.
Will I be flooded with alerts?
No. An engineer triages alerts against your baseline before they reach you, so a plugin update you made is not treated as an incident. The goal is a handful of alerts you trust, not a stream you learn to ignore.
Does monitoring help with PCI DSS or ISO 27001?
Yes. It supports PCI DSS logging and file-integrity monitoring under requirements 10 and 11.5, and ISO 27001 Annex A logging and monitoring controls. We provide records and reports structured to evidence those controls.
Can you monitor a site you did not build or secure?
Yes. We onboard any site: we capture a baseline of its files, users and configuration first, then monitor against it. Many clients come to us for monitoring after a scare on a site someone else built.
Do I still need penetration testing if I have monitoring?
Yes, they do different jobs. Website security testing finds the flaws before attackers do; monitoring catches the compromises and regressions that happen between tests. Together they cover both the known and the unexpected.
Is my data kept confidential?
Always. Monitoring runs under an NDA, and anything we observe about your site is shared only with the people you name. As a European provider we handle your data accordingly.
