Architecting Resilient Infrastructure.
Native Linux Security.
We are a UK-registered IT security company specializing in automated hardening packs, turnkey server fortification, and comprehensive vulnerability assessments for mission-critical Linux environments.
Engineered to Protect Critical Linux Infrastructure
Khodshima Sumn Assist LTD was established by seasoned Linux systems engineers and defensive security practitioners who recognized a critical flaw in modern cloud hosting.
The Genesis: Why We Started
Every minute, thousands of newly provisioned cloud servers on AWS, Hetzner, DigitalOcean, and OVH are probed by automated global botnets. Standard default operating system installations leave critical surfaces wide open: generic SSH port configurations, unconstrained memory subsystems, permissive sudo policies, and unmonitored local ports.
For years, the cybersecurity market offered two imperfect extremes: either ignore the threat until a ransomware or cryptojacking incident occurs, or pay exorbitant monthly subscriptions for bloated third-party SaaS agents that consume 500MB+ RAM and introduce their own unvetted root vulnerabilities.
Khodshima Sumn Assist LTD was created to deliver a third, uncompromising path: native, kernel-level fortification. We engineer robust, battle-tested configurations that operate directly within the Linux kernel—delivering enterprise-grade security with 0.01% CPU overhead, zero external dependencies, and complete client data sovereignty.
From Script Automation to Turnkey Engineering
What began as internal hardening playbooks evolved into an automated suite of production-ready scripts, tailored for Ubuntu, Debian, AlmaLinux, and RHEL.
Continuous Availability Deployment Protocol
We developed strict staged execution protocols with atomic backups and dry-run syntax checks, enabling us to fortify live production servers without disconnecting active customer traffic.
UK Corporate Registration & Accountability
We established our official UK corporate entity to provide clients with legal contracts, commercial invoicing, signed Non-Disclosure Agreements, and clear technical warranties.
Enterprise Compliance & Multi-Node Defense
Today, we fortify everything from single VPS nodes for growing businesses to complex multi-server VPC clusters compliant with CIS Benchmarks, PCI-DSS, and GDPR standards.
Enterprise-Grade Protection
We help SaaS startups, e-commerce stores, fintech platforms, and hosting providers transform vulnerable cloud servers into fortified bastions compliant with international security standards.
Engineered for Uptime
We understand that production servers cannot afford downtime. Our deployments are staged, validated with dry-run tests, and executed without interrupting ongoing customer transactions or active sessions.
Legal Accountability
Operating as a legally registered UK entity, we offer transparent commercial agreements, formal invoices, and 30–60 days of post-installation warranty with verified CIS Benchmark compliance reports.
Engineered with Precision & Integrity
Four pillars that govern every line of code, hardening script, and client engagement:
Native Subsystems over Heavy Bloatware
Many commercial security suites require installing bloated background agents that consume 500MB+ RAM, drain CPU cycles, and introduce new attack vectors. We engineer security natively using built-in Linux kernel subsystems (NFTables, sysctl, pam, auditd, fail2ban) resulting in 0.01% system overhead.
Ephemeral Access & Clean Handover Protocol
During turnkey installations or vulnerability audits, our engineers connect exclusively using temporary, client-approved Ed25519 SSH keys. Upon completion and client verification, our keys are purged and our access is severed completely.
Non-Destructive Staged Deployment
Every configuration rollout is pre-validated with dry-run syntax checks (e.g. sshd -t, nginx -t) and backed up atomically to /var/backups/. Active SSH connections, live web traffic, and databases stay online without interruption.
UK Corporate Accountability & SLAs
We are a registered United Kingdom corporate entity. Every engagement is backed by formal commercial invoicing, strict non-disclosure obligations, and a minimum 30 to 60-day post-installation technical warranty.
Native Linux Hardening vs Bloated SaaS Agents
Many commercial security suites require installing bloated background agents that consume 500MB+ RAM, drain CPU cycles, and run as unaudited root-level black boxes.
At Khodshima Sumn Assist LTD, we believe the most secure server is the one that leverages the rock-solid, battle-tested subsystems already built into the Linux kernel (NFTables, sysctl, pam, auditd, fail2ban).

Transparent 5-Step Delivery Model
How we execute security deployments from initial diagnostic to verified handover:
Scope Discovery & Threat Mapping
We analyze your server stack, exposed network ports, and regulatory compliance targets to choose the exact hardening profile.
Atomic Configuration Backup
Our engine generates a timestamped snapshot of /etc/ssh, /etc/sysctl.d, and network configs to /var/backups/ for instant rollback.
Dry-Run & Staged Execution
Security parameters, firewall rules, and PAM rate-limits are deployed without disconnecting active admin sessions.
Lynis CIS Benchmark Verification
An automated diagnostic scan confirms that all attack vectors are locked down and the CIS compliance score is 95+.
Handover & Access Purge
Final deliverables, playbooks, and reports are delivered to your team. All temporary keys are purged immediately.
Legal Entity & Governance
Khodshima Sumn Assist LTD operates under full United Kingdom commercial law with complete accountability.
