Features and specs

What each product offers, as listed by its team.

VIESAC 4 features
CloudLinux 5 features
  • Accessibility
    VIESAC provides an online platform that is easy to access, allowing users from various locations to benefit from its services without geographic limitations.
  • Comprehensive Information
    The platform offers detailed and extensive information, making it a valuable resource for users seeking specific data or insights.
  • User-friendly Interface
    VIESAC is designed with an intuitive interface, making navigation simple and efficient for all users, including those with limited technical skills.
  • Timely Updates
    The platform ensures that the information provided is current and regularly updated, enhancing its reliability and relevance for users.
  • 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

  • I don't have verified information about VIESAC (viesac.eu), so I cannot confirm whether it is a good or trustworthy service. Please treat this response as general guidance rather than a factual endorsement, and verify the company's legitimacy independently before using it.

Why this product is good

  • I cannot confirm the company's reputation, ownership, or track record from reliable sources
  • Always check for verifiable contact details, a physical address, and company registration information
  • Look for genuine independent reviews on trusted third-party platforms rather than testimonials on the site itself
  • Confirm the site uses secure connections (HTTPS) and clear terms of service, privacy, and refund policies
  • Be cautious of offers that seem too good to be true, as these can be warning signs of scams

Recommended for

  • Users who have independently verified the company's legitimacy and credentials
  • Customers who have confirmed positive reviews from trusted, independent sources
  • Anyone willing to start with a small, low-risk transaction before committing further
  • People who have checked the site's security, policies, and customer support responsiveness

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 VIESAC and CloudLinux.

What makes your product unique?

VIESAC's answer

VIESAC goes beyond basic VAT number validation by combining real-time checks, resilient fallback routing, and audit-ready evidence in one platform.

Unlike standard VAT lookup tools, VIESAC can automatically use alternative official registries when VIES is unavailable, helping businesses keep validation workflows running without interruption.

Each verification can be stored with timestamped evidence and generated as a professional PDF or XML certificate for audits, tax reviews, and internal compliance.

VIESAC also supports API integrations, WooCommerce, Google Sheets, EORI validation, monitoring, and country-specific business registries — making it suitable for both occasional checks and automated high-volume compliance workflows.

The focus is not only on answering “Is this VAT number valid?” but on providing reliable, reusable proof of the verification.

Why should a person choose your product over its competitors?

VIESAC's answer

VIESAC is built for businesses that need more than a simple VAT lookup.

It combines VAT and EORI validation, SmartRouter™ fallback checks, audit-ready PDF/XML certificates, monitoring, API access, and integrations in one platform.

A key advantage is reliability: when VIES is unavailable, VIESAC can use alternative official sources where supported, reducing failed checks and interruptions.

It also keeps structured evidence of each verification, so businesses can demonstrate when and how a VAT number was checked during audits, tax reviews, or internal compliance processes.

Compared with basic validation services, VIESAC focuses on the complete compliance workflow — from verification to evidence, monitoring, and automation — while remaining simple enough for occasional manual use.

How would you describe the primary audience of your product?

VIESAC's answer

VIESAC is primarily designed for businesses that regularly sell to, buy from, or verify companies across borders and need reliable VAT compliance evidence.

Typical users include e-commerce businesses, wholesalers, logistics companies, automotive traders, accounting and tax teams, procurement departments, universities, public-sector organizations, and software platforms that need automated VAT or EORI validation.

It is especially useful for companies handling EU B2B transactions, reverse-charge sales, supplier onboarding, customer verification, or recurring compliance checks.

VIESAC serves both small businesses that need occasional verified checks and larger organizations that require API integrations, monitoring, audit trails, and higher-volume automated workflows.

What's the story behind your product?

VIESAC's answer

VIESAC started from a simple problem: VAT validation is easy when everything works, but real-world compliance is much more complicated.

Businesses need to know not only whether a VAT number is valid, but also when it was checked, which source confirmed it, what happened if VIES was unavailable, and whether they can prove the verification later during an audit.

VIESAC was built to solve that gap.

What began as a reliable VAT validation service gradually evolved into a broader compliance platform with audit-ready evidence, PDF and XML certificates, monitoring, API access, EORI validation, country-specific registries, and integrations for business workflows.

The goal has remained the same from the beginning: make cross-border VAT verification more reliable, easier to automate, and easier to prove.

Which are the primary technologies used for building your product?

VIESAC's answer

VIESAC is built around modern web and integration technologies, including REST APIs, webhooks, OAuth-based integrations, structured JSON/XML data exchange, and cloud-based automation.

The platform connects with official VAT, EORI, tax, and business registries and supports integrations with e-commerce, spreadsheets, automation platforms, and other business systems.

VIESAC is designed to work both as a standalone web application and as an API-first compliance service that can be embedded into existing business workflows.

Who are some of the biggest customers of your product?

VIESAC's answer

VIESAC is used by businesses and organizations across several sectors, including automotive and vehicle trading, logistics and freight, wholesale and distribution, e-commerce, accounting and tax advisory, legal services, universities, and public-sector organizations.

The platform is particularly relevant for companies that handle frequent cross-border B2B transactions and need reliable VAT or EORI validation together with audit-ready evidence.

VIESAC is also used by larger organizations evaluating API-based or automated compliance workflows for higher-volume verification.
