We Know You've Been There
The 3AM Phone Call
Your client's website is down, sales are bleeding, and you're scrambling to figure out what went wrong. Downtime costs SMBs $300/hr on average*.
The TLS Surprise
Certificate expired without warning, browsers showing scary warnings, and trust evaporating by the minute - dropping your search rankings along with it.
The Security Breach
A vulnerability you didn't know existed became an attack vector. Fact: 93% of WordPress vulnerabilities come from outdated plugins*.
These crisis moments don't have to happen. Let us be your early warning system.

The Real State of Website Security
We conducted an outside-in, passive security audit across 32,036 live websites. The data reveals why internal assumptions fail and continuous external monitoring is vital.
Domains Audited
Scanned 100% passively from the outside with zero plugins installed.
Outdated Plugins
19,616 domains running at least one outdated or vulnerable plugin.
Non-Latest Core
15,968 domains running below newest release (including 6-day patch lag).
Critical Legacy Cores
6,561 domains stranded on legacy, unmaintained major branches (v6/v5/v4).
Routine Patch Lag vs. Legacy Stranding
When WordPress releases a new minor update, staging review windows are standard procedure. In our dataset, the latest release had landed just 6 days earlier, and 29.3% of sites (9,407 domains) were running the immediate prior release.
The critical risk is legacy stranding: over 20% of all scanned websites (6,561 sites) are completely abandoned on legacy major branches (v6.x, v5.x, v4.x, down to v2.0.11) with publicly documented, weaponized CVEs.
Why sites get stranded: Custom theme and plugin incompatibilities, hardened server configs disabling WP-Cron, or orphaned client projects where maintenance lapsed.
High Market Concentration Attracts Botnets
WordPress core vulnerabilities are relatively rare, but third-party plugins account for over 90% of all real-world entry points.
Extreme concentration multiplies exposure: just 3 popular plugins powered a massive share of the detected attack surface: Yoast SEO (31.9%), Elementor (21.4%), and Contact Form 7 (15.4%).
Why attackers automate: When high-profile CVEs drop in popular extensions (like Really Simple Security CVE-2024-10924 or LiteSpeed Cache CVE-2024-28000), automated botnets scan IPv4 ranges within 24 to 48 hours looking for matching asset fingerprints.
The Agency Supply Chain & Shared Blueprint Risk
Standardized starter templates are smart engineering for digital agencies, cutting setup time from days to minutes and maintaining codebase consistency across client portfolios.
However, this shared architecture creates an inherent blast radius: our crawler hop analysis discovered single agency networks linked to thousands of client domains. When a base template contains an unpatched plugin or pinned core, every client website launched from that blueprint inherits the identical vulnerability.
Fleet-wide defense: Outside-in monitoring gives agencies continuous visibility across their entire client roster from a single dashboard without installing intrusive software on client servers.

We take care of the tedious things, so you can rest (or do overtime and work on client projects):
- Uptime
- TLS certificates
- Webserver and CMS version fingerprinting, including plugins (e.g. WordPress)
- Security vulnerability alerts based on detected software versions
- Defacement Detection
- Broken Link Detection
- DNS issues
- Spam-lists
- And more - take a look at our Roadmap
Absolutely! Agencies are a big focus group, because we know how hard it is to keep track of 20, 50, 100 websites. More details can be found on our public Roadmap. Stay tuned!
We check your domains continuously to ensure they are available and secure. Here is how and when we check:
- CMS Version Fingerprints: Checked 4 times a day with negligible impact on your website's performance - you won't even notice it.
- Uptime: Checked every minute (subject to change after the Founder Preview). If down 3 times in a row, we send an alarm. For example: Your subscription checks the website every minute. Your website doesn't answer for 3 minutes, we'll send an alarm.
- TLS Certificates: Checked once a day to ensure they are valid and not expiring soon.
- Vulnerability Alerts: Checked continuously as new vulnerability data is published. When a match is found for your detected CMS version, you'll be notified.
No, Vioro uses a 100% outside-in website security monitoring approach.
Outside-in monitoring inspects website uptime, TLS certificates, and CMS component vulnerabilities from the external perspective of a browser or attacker without requiring server plugins or code installations. This eliminates plugin maintenance overhead, prevents server performance degradation, and avoids introducing new PHP attack surfaces.
Yes, of course!
While we proudly host our infrastructure within the EU to guarantee strict GDPR compliance and immunity from the US CLOUD Act, Vioro can monitor websites located anywhere in the world.
Our outside-in approach means it doesn't matter where your servers or clients are located. You get the same reliable monitoring and vulnerability detection globally.
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) both encrypt the connection between a browser and a server, but SSL is the older, now deprecated predecessor. Every SSL version has known security vulnerabilities and has been officially retired.
TLS picked up where SSL left off and is the protocol your browser actually uses today. When someone says "SSL certificate," they almost always mean a certificate used with TLS.
At Vioro we use the correct term "TLS" to be precise and to reinforce that your sites should be running on a modern, secure protocol.
