Features and specs

What each product offers, as listed by its team.

Guide.MD 5 features
CloudLinux 5 features
  • Profiles for every US provider
    10.5 million clinicians, practices and hospitals, built from the official NPI registry and CMS data.
  • Claim and correct your profile
    Take over your profile in about 2 minutes; no ID needed with a practice, hospital or institutional email.
  • AI assistant visibility
    Structured, machine-readable profiles that ChatGPT, Claude, Perplexity and Gemini read about 2 million times a day.
  • Condition pages and badges
    Appear on each condition and procedure page you treat in your city, with badges like accepting new patients and telehealth.
  • Practice and agency accounts
    Practices manage all their providers from one login; marketing agencies manage client profiles and earn an affiliate share.
  • 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.

Why this product is good

  • 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 Guide.MD and CloudLinux.

Which are the primary technologies used for building your product?

Guide.MD's answer

  • WordPress with a custom PHP directory plugin
  • MySQL for the provider records
  • Cloudflare for delivery and for counting AI assistant and search engine reads
  • schema.org structured data on every profile, so search engines and AI can parse it
  • Weekly NPI registry (NPPES) and CMS data updates

Who are some of the biggest customers of your product?

Guide.MD's answer

  • Independent physicians and dentists
  • Therapists, psychologists and other mental health providers
  • Chiropractors, podiatrists and physical therapists
  • Group practices and clinics
  • Healthcare marketing agencies

Why should a person choose your product over its competitors?

Guide.MD's answer

Most directories run on ads, paid placement or anonymous reviews, and the provider has little say in what they show. Guide.MD starts from official records and lets the provider take over and correct the profile, with no charge to claim it. Claimed profiles list the conditions and procedures a provider actually treats and appear on those pages for their city. Guide.MD also publishes how often AI assistants read it, so providers can see who is reading their profile.

What makes your product unique?

Guide.MD's answer

Guide.MD has a profile for every licensed healthcare provider in the United States, 10.5 million clinicians, practices and hospitals, built from the official NPI registry and CMS data rather than scraped listings. Providers can claim their own profile in about two minutes and correct it. And it is written for AI: profiles are structured, machine-readable pages that AI assistants such as ChatGPT, Claude and Perplexity read about 2 million times a day, so an accurate Guide.MD profile is how a provider shows up when patients ask an AI for a doctor.

How would you describe the primary audience of your product?

Guide.MD's answer

  • Physicians, dentists, therapists, chiropractors, podiatrists, nurse practitioners and other licensed clinicians who want an accurate profile patients and AI assistants can find
  • Practices and hospitals managing several providers from one login
  • Healthcare marketing agencies keeping their clients' profiles accurate
  • Patients, attorneys and companies looking for a provider by condition, procedure, city, or for expert witness and consulting work

What's the story behind your product?

Guide.MD's answer

Guide.MD was founded by Pouyan Golshani, MD, an interventional radiologist in Los Angeles. He saw that the facts about a doctor's work lived on directories that copy each other and go stale, and that patients were starting to ask AI assistants for doctors. AI repeats whatever it can read. So Guide.MD builds every provider's profile from official records and lets the provider correct it, giving patients, search engines and AI assistants one accurate source.
