High-Performance Multi-Tenant Hosting Operations

cPanel/WHM powers millions of websites worldwide. We ensure your shared, reseller, and dedicated cPanel servers deliver peak execution speeds, zero spam blacklisting, and rock-solid isolation between accounts.

EasyApache 4 & LiteSpeed Caching

Optimizing worker MPM event models, fine-tuning PHP-FPM process pools for low memory footprints, implementing Redis object caching, and integrating LiteSpeed Enterprise when ultra-high concurrency is required.

Exim Spool & Deliverability Protection

Real-time monitoring of outbound email volume per cPanel account, configuring custom RBL blacklists, automatic quarantine of compromised mailboxes, and automated SPF/DKIM key generation.

Engineering Scope & Deliverables

Concrete administration, tuning, and incident resolution capabilities for this environment.

Core WHM

WHM Configuration & Security

Tweak Settings optimization, root access hardening, cPHulk brute-force protection, and ModSecurity WAF rulesets.

Web Stack

EasyApache 4 & MultiPHP-FPM

Custom EasyApache profiles, OPcache tuning, Brotli compression, PHP extension compiling, and per-domain PHP-FPM socket pools.

Mail Stack

Exim & Mail Deliverability

Resolving stuck mail queues, investigating outbound spam origins, fixing frozen spools, and configuring DNS SPF/DKIM/DMARC.

Hosting OS

CloudLinux & CageFS Integration

LVE Manager resource limits (CPU/Memory/IOPS), CageFS skeleton maintenance, and MySQL Governor database isolation.

High Concurrency

LiteSpeed Web Server Integration

Installation and tuning of LiteSpeed Web Server (LSWS) with LSCache, converting Apache configs, and handling license activations.

Migrations

Transfer Tool & Account Migrations

Full server-to-server migrations using WHM Transfer Tool with zero data loss, DNS cluster sync, and SSL certificate continuity.

How Support Engagements Work

Structured, transparent workflows designed to preserve uptime and eliminate surprises.

01

WHM Audit

Audit EasyApache 4 profiles, MySQL memory allocation, Exim mail queues, and active security plugins.

02

Stack Tuning

Convert domains to PHP-FPM pools, configure OPcache, and tune MariaDB InnoDB buffer pool sizes.

03

Hardening & WAF

Deploy OWASP/COMODO ModSecurity rules, configure CSF firewall, and enable cPHulk protection.

04

Backup & Verification

Configure JetBackup 5 offsite destination jobs and establish automated health monitoring.

Zero-Credential Form Policy

Please do not submit root passwords, private SSH keys, sudo tokens, or database secrets through website intake forms. When you initiate an engagement, our engineers establish an ephemeral encrypted exchange channel.
Engineering FAQ

Frequently Asked Questions

Clear answers about operational models, access security, and engineering scope.

01 Can you troubleshoot blocked or frozen Exim mail queues in cPanel?

Yes. Our engineers inspect exim_mainlog, identify compromised scripts sending unauthorized bulk email, clear frozen spools, and configure rate limits in WHM Tweak Settings.

02 Do you support CloudLinux and CageFS on cPanel servers?

Yes. We manage CloudLinux installations, configure LVE Manager limits (CPU, memory, concurrent connections, IOPS), and rebuild CageFS user skeletons.

03 Can you help migrate all cPanel accounts from an old server to a new one?

Yes. We use the WHM Transfer Tool or automated rsync scripts, sync MySQL databases, verify DNS cluster propagation, and ensure SSL certificates remain active with zero downtime.

04 How do you resolve AutoSSL / Let's Encrypt renewal errors?

We debug Domain Control Validation (DCV) pre-flight check failures, inspect .htaccess rewrite rules blocking the .well-known directory, and force certificate renewals.
