cPanel/WHM & CSF Firewall Security — Wandzilak Web Design

THE REALITY OF SHARED HOSTING

Most "Managed" Hosting Is Just
Managed Neglect.

Every day, thousands of WordPress sites get compromised on servers that haven't been hardened. Default cPanel installs. No firewall rules. PHP running as nobody. Mail ports wide open. The host's idea of "security" is a checkbox on a marketing page.

We've been managing cPanel/WHM environments for years. We know what a properly configured server looks like — and we know the gap between that and what most clients inherit when they come to us. The difference between a site that survives and one that gets owned is almost always configuration, not cost.

OUR PHILOSOPHY

cPanel Is the Control Plane.
CSF Is the Guard Dog.

cPanel and WHM aren't just hosting control panels — they're the command center for everything that happens on a Linux web server. User accounts, email routing, DNS zones, SSL management, PHP version control, cron jobs, backups. When you're fluent in cPanel/WHM, you control the entire stack.

"We are cPanel/WHM seasoned. We know the platform inside and out — and when we layer CSF on top, we build servers that attackers genuinely give up on."

CSF — ConfigServer Security & Firewall — is the industry's most capable Linux firewall for cPanel environments. It goes far beyond basic iptables rules: login failure detection, port scan protection, connection tracking, SMTP authentication enforcement, and real-time block list integration. Properly configured, it transforms a standard VPS into a hardened server.

WHAT WE BRING TO YOUR SERVER

Six Layers of
cPanel/CSF Expertise

Server security isn't a product — it's a posture. Here's how we build it.

01

CSF Firewall Configuration

Port rules, connection limits, login failure thresholds, SMTP lockdowns, and real-time IP reputation blocking. Not defaults. Not click-through setup. Precision-tuned from the command line.

02

Brute Force Mitigation

CSF's LFD daemon watches every authentication attempt across SSH, FTP, webmail, and WordPress — and auto-bans attackers after configurable failure thresholds, before they reach your application.

03

WHM Server Management

Multi-account WHM environments, reseller setups, package limits, resource quotas, and PHP version management per account. We've run WHM environments managing dozens of live sites simultaneously without incident.

04

Mail Security & Deliverability

SPF, DKIM, DMARC, BoxTrapper, SpamAssassin, and outbound SMTP rate limiting via CSF. Your email lands in inboxes, not spam folders, and your IP reputation stays clean.

05

Malware Scanning & Cleanup

ClamAV integration, LMD (Linux Malware Detect), and manual auditing of suspicious file patterns. When a site gets hit, we find every injected file — not just the obvious ones. Then we determine how they got in.

06

SSL, Backups & Hardening

AutoSSL for every domain, automated off-server backup schedules, PHP handler hardening (suPHP/suEXEC), open_basedir restrictions, and disabling dangerous PHP functions — the full security checklist, actually checked.
