The Problem

Why teams come to us for server management & hardening

Keep your Linux servers secure, patched, and optimized. Sloctech provides expert Linux system administration—configuring UFW/iptables firewalls, installing Fail2ban brute-force defenses, tuning Nginx/Apache workers, configuring MySQL query memory pools, and monitoring CPU and RAM usage continuously.

What We Build

Included in every Server Management & Hardening engagement

Firewall & Fail2ban

Blocking abusive IP subnets and automated SSH brute-force attempts.

Web Server Tuning

Configuring Nginx micro-caching, gzip/brotli compression, and worker limits.

Database Tuning

Optimizing MySQL innodb_buffer_pool and slow query logs.

Offsite Backups

Automating encrypted database & file backups to AWS S3.

Deliverables

What you receive

Hardened Linux OS Environments Protected Against Cyber Attacks
Optimized Nginx/PHP-FPM/MySQL Memory Allocation for High Speed
Automated Nightly Server Backups with Offsite Storage Retention
Continuous server health monitoring with immediate downtime alerts

Process

Discovery to delivery to support

01
Server Security Audit

Checking open ports, outdated OS packages, and user access privileges.
02
Hardening & Patching

Applying security kernel patches, closing unused ports, and locking SSH.
03
Performance Optimization

Tuning PHP-FPM pool sizing and database buffer pools.
04
Ongoing Monitoring Setup

Deploying UptimeRobot or Datadog agents for continuous telemetry.

Scope, Cost & Ownership

What drives the number on your quote

Cost factors

Number of distinct user roles and the permission rules between them
Third-party systems to integrate, and how well documented their APIs are
Whether existing data has to be migrated, and what condition it is in
Depth of custom design versus adapting an established design system
Compliance or audit requirements that change how we build and test

We quote after a scoping call, itemised by module, so you can see what each part costs and drop anything you do not need.

Typical timeline

Timelines follow scope, so we give you one at the end of discovery rather than before it. What we can commit to up front is the shape of the schedule:

Discovery and a written scope before any build work starts
Working software demonstrated on a fixed sprint cadence, not just at the end
A dated delivery plan you approve before we commit to it

What you own

Full copyright in the source code we write for you, assigned on final payment
The repository, its history, and the deployment configuration
Database schemas, migrations and technical documentation
Accounts and infrastructure registered in your name, not ours

Third-party libraries keep their own open-source licences, and any commercial component is listed in the quote before you sign.
