About Tessio and CloudLinux

In their own words, as submitted to SaaSHub.

Tessio
CloudLinux

Tessio is an age and identity verification API built on the EU Digital Identity Wallet. Most age assurance today means uploading an ID document or taking a selfie. That solves the regulator's problem by creating a data protection one, because you then hold identity data you have to secure,...

Features and specs

What each product offers, as listed by its team.

Tessio 8 features
CloudLinux 5 features
  • Wallet-native age checks
    Proves 18+ (or any of thirteen age thresholds) from the EU Digital Identity Wallet. The user approves the request on their own device.
  • No personal data received
    The credential we request carries age booleans only: no name, no date of birth, no document number, no photo. There is nothing to store or breach.
  • One API call
    Start a check with a single REST call, get back a link or QR code, receive the signed result on your webhook.
  • Signed webhooks
    Results delivered with an HMAC-SHA256 signature and timestamp, so you can verify authenticity and detect replays.
  • Both EU credential formats
    SD-JWT VC and ISO mdoc, the two formats the EU wallet ecosystem uses. The verifier underneath passes the OpenID Foundation conformance suite in both.
  • Sandbox included
    Integrate and test end to end today; checks complete in about two seconds against the sandbox.
  • Open source core
    The verifier library is Apache-2.0 on NuGet, so you can read exactly what the crypto does before trusting it.
  • EU hosted
    Runs entirely on EU infrastructure (Finland). Data never leaves the EU.
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.

Overall verdict

  • CloudLinux is a well-regarded, mature Linux OS distribution and toolset specifically designed for shared hosting and multi-tenant server environments, offering strong isolation, resource management, and security features that make it a solid choice for hosting providers.

Why this product is good

  • Provides LVE (Lightweight Virtual Environment) technology for per-tenant resource isolation, preventing 'bad neighbor' effects on shared servers
  • Enhances server stability and security by isolating users so that one account's issues (crashes, resource spikes) don't affect others
  • Offers extended lifecycle support (longer than standard CentOS/RHEL support windows), which is valuable for legacy systems
  • Includes tools like CloudLinux OS Shield, Imunify360 integration, and hardened kernel options for improved security
  • Compatible with popular control panels like cPanel and Plesk, making it easy to integrate into existing hosting stacks
  • Backed by an established company with a long track record in the hosting industry and responsive support
  • Offers granular control over CPU, memory, I/O, and other resources per user account
  • Provides PHP Selector and multiple PHP version support, useful for hosting providers serving diverse client needs

Recommended for

  • Web hosting companies running shared or reseller hosting environments
  • Hosting providers needing to isolate customer accounts on the same physical server
  • Businesses requiring extended OS support lifecycles beyond standard RHEL/CentOS EOL dates
  • Enterprises using cPanel or Plesk that want tighter security and resource control
  • Hosting companies looking to reduce support tickets caused by noisy-neighbor resource contention
  • IT teams managing multi-tenant infrastructure who need governance and monitoring tools built into the OS layer

Questions & Answers

As answered by people managing Tessio and CloudLinux.

What makes your product unique?

Tessio's answer

Tessio verifies age from the EU Digital Identity Wallet instead of collecting documents or selfies. The credential it requests carries age booleans and nothing else: no name, no date of birth, no document number, no photo. That means there is no identity data to store, leak or audit, and it is a property of the protocol rather than a promise, so you can verify it yourself. The verifier underneath is open source and passes the OpenID Foundation conformance suite for OpenID4VP 1.0 HAIP verifiers in both EU credential formats.

Why should a person choose your product over its competitors?

Tessio's answer

Most age verification vendors solve the regulator's problem by creating a data protection one: you end up holding ID documents or biometric data. Tessio asks a narrower question and receives a narrower answer, a signed yes or no. For platforms under the UK Online Safety Act, the EU Digital Services Act or gambling licences, that removes the breach surface and most of the GDPR overhead instead of managing it. And because the verification core is open source, a technical reviewer can check the claims before ever talking to us.

How would you describe the primary audience of your product?

Tessio's answer

Compliance and product teams at age regulated platforms in the EU and UK: iGaming operators, nicotine and alcohol e-commerce, dating and social apps, and the platform providers that serve them. The integration is a REST API with webhooks, built to be wired in by one developer in an afternoon.

What's the story behind your product?

Tessio's answer

Tessio is built by a small studio in Stockholm (Triple Down AB). The starting point was a regulatory collision: age checks are becoming mandatory across Europe while the usual methods, document upload and face scanning, create exactly the data protection risk the same regulators punish. The EU Digital Identity Wallet made a third way possible for the first time: a credential that proves an age threshold and contains nothing else. We built the verifier, open sourced it, ran it through the OpenID Foundation conformance suite, and put a hosted API on top. It is early and access is invite only, and the site says so plainly.

Which are the primary technologies used for building your product?

Tessio's answer

.NET and ASP.NET Core, PostgreSQL and Valkey, a Next.js dashboard, all running on EU infrastructure. The protocol layer is OpenID4VP 1.0 with SD-JWT VC and ISO 18013-5 mdoc credentials. The verifier library, Tessio.Verifier, is Apache-2.0 on NuGet.
