The Problem

Your Server Went Live With the Settings It Shipped With

It shows up after a quick launch or a contractor hand-off. The server works fine, answers on ports nobody uses, and nobody has checked it against a hardening standard.

  1. Password logins

    Your SSH accepts passwords, and root can sign in remotely.

    Password logins

    Key-only SSH, no remote root, and failed logins banned automatically.

  2. Open ports

    Your database and an old admin panel face the internet.

    Open ports

    Every listening port is closed or written down with the reason it stays open.

  3. Chatty servers

    Your error pages announce the web server and PHP versions.

    Chatty servers

    Version banners, directory listings, and debug output are switched off.

  4. Old protocols

    Outdated TLS versions and weak ciphers are still accepted.

    Old protocols

    TLS 1.2 and 1.3 only, with a cipher list that current browsers support.

Your web server was set up in a hurry three years ago, and it has run fine since. SSH still accepts passwords, and root can log in. The database listens on a public port. NGINX announces its version on every error page, and an old TLS version is still switched on. A forgotten admin panel answers on port 8080. Nothing is broken, which is exactly why nobody has looked.

We start with a scan against the CIS Benchmark for your operating system, then rank every failed check by risk. Changes go in small batches on a snapshot or staging copy first, with a rollback note for each. SSH, ports, services, the web server, and the runtime all get locked down. You get a before and after score, not just a promise that it's safer.

  • Scored against CIS Benchmarks

    Every server is scanned before and after, so you see which checks passed and why.

  • Snapshot before every change

    Changes go in small batches with a tested way back, so a setting can't take the site down.

  • A record of every setting

    You get a hardening log listing each change, the reason, and any check left open on purpose.

Our Server Hardening Services Process

From Baseline Scan to Signed-Off Server in Five Clear Steps

You see the scan results before anything changes, approve each batch of settings, and get a final score with every exception written down.

  1. You get an outside scan of your open ports, TLS settings, and version banners. Your note shows what an attacker can see today, plus a fixed price. If your host already hardens the server and you have no root access, we'll tell you before we quote.

Projects We've Built

E-learning, NFT marketplace, payroll, and trading platforms we designed and built. They weren't hardening projects, but each runs on servers like the ones this service locks down.

What's Included

What You Get With Linux and Windows Server Hardening

You get access lockdown, closed ports, trimmed services, and a hardened web server and runtime. Logging catches tampering, and benchmark scores show where you started and finished.

  • Access lockdown

    Key-only SSH or locked-down RDP, no shared admin accounts, and sudo rights trimmed to the people on your team who need them.

  • Firewall and port review

    Every listening port on your server mapped, unused ones closed, and your database bound to localhost or a private network.

  • Web server lockdown

    NGINX, Apache, or IIS set to hide versions, block directory listings, enforce TLS 1.2 or later, and send security headers.

  • Runtime and file permissions

    PHP, Node.js, or .NET settings tightened, secrets moved out of the web root, and file ownership fixed.

  • Audit logging

    auditd or Windows audit policy capturing logins, privilege changes, and edits to key files, sent to one place.

  • Benchmark report and log

    Before and after CIS scores, every change with its reason, and each check left open on purpose.

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have built websites, platforms, and apps for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why Teams Trust Us to Follow Server Hardening Best Practices

Hardening fails when it breaks production or gets undone a month later. These habits keep your server hardening services work safe, provable, and lasting.

  • Snapshot first, every time

    Your server gets a snapshot or backup before each batch of changes. If a setting breaks something, you roll back instead of rebuilding.

  • Small batches, tested between

    Your server changes one area at a time, with your site, logins, and jobs tested before the next. If something breaks, you know which setting did it.

  • Exceptions in writing

    Some benchmark checks don't fit your app, and that's normal. Each one we leave open is written down with the reason, so an auditor sees a decision, not a miss.

  • Scores, not promises

    You get the benchmark score before and after the work. If a number didn't move, you'll see that too, along with what's holding it back.

  • Honest about managed hosting

    If your host controls the server and you don't have root, there's little to harden at the OS level. We'll say so and point you to what you can change.

  • Your access, your keys

    You create our accounts, and you remove them when we finish. No keys, passwords, or extra users stay behind after handover.

Good fit

  • Teams self-hosting a web app

    Your app runs on a VPS or cloud server your developer set up, and nobody has checked it against a hardening standard since launch.

  • Businesses facing a security questionnaire

    Your customer or insurer asks which server hardening standards you follow, and you need a CIS baseline with a real score behind your answer.

  • Windows Server shops

    Your site or line-of-business app runs on IIS, and you want Windows server hardening that won't break the tools your staff rely on.

  • Sites after a security scare

    Your server was flagged by a scanner or hit by brute-force logins, and you want website hardening at the server layer, not just a plugin.

  • Agencies hosting client sites

    Your agency runs client sites on its own servers and wants one tested baseline applied to every box, with a log for each client.

Not a fit

  • Want ongoing server care

    You need someone to patch, watch, and back up your servers every month. Our Server Management Services cover that from $350 per month.

  • Only monthly patching

    Your servers are already locked down, and you just need updates applied in tested rings. Our Patch Management Services fit that better.

  • Managed host, no root

    Your WordPress site lives on managed hosting with no server access. Our WordPress Security Services harden what you can actually change.

  • Need a company-wide review

    You need all 18 CIS Controls assessed across your company, not individual server settings. Our CIS Controls Assessment covers that scope.

FAQ

Frequently Asked Questions

Straight answers on cost, timing, what hardening means, Linux and Windows, techniques, and what happens after handover.

  • Server hardening services from DeveloperLook start at $650 for one Linux or Windows server, with a CIS Level 1 scan before and after. The $1,650 plan covers up to 4 servers in one stack, including the database and runtime. The $3,400 plan covers up to 12 servers, with the settings kept as Ansible or Group Policy code.

  • One server takes about 1 week, including the scan, your approval, and tested change batches. A stack of up to 4 servers takes 2 to 3 weeks, and 12 servers take 4 to 6 weeks. Most of the time goes into testing between batches, because that's what keeps your site running.

  • Server hardening is the work of making a server harder to attack by removing what it doesn't need and tightening what it keeps. You close ports, remove unused software, limit who can log in, turn on logging, and change insecure defaults. NIST's Guide to General Server Security (SP 800-123) describes the same approach.

  • A hardened server runs only the services it needs, accepts logins only from approved people and keys, and logs who does what. Its settings match a written standard, such as a CIS Benchmark, with your exceptions recorded. You can prove it with a scan score instead of taking someone's word for it.

  • For a website, it means locking down the machine your site runs on, not just the site itself. Plugins and app settings protect the website. Hardening protects the layer below it: SSH or RDP access, open ports, the web server, the runtime, and file permissions. Attackers often get in at that layer.

  • Common techniques are key-only SSH, removing unused packages and services, closing unused ports, and binding your database to localhost. You also hide version banners, enforce TLS 1.2 or later, and set strict file permissions. Audit logging and automatic security updates round it out. A server hardening checklist such as a CIS Benchmark lists each check with its exact setting.

  • Linux server hardening means applying a baseline such as the CIS Benchmark for Ubuntu, Debian, or Red Hat. On your server, that means key-only SSH with root login off, a host firewall with nftables or ufw, and fail2ban for repeated failed logins. You add auditd, unattended security updates, and tighter kernel settings, then measure with OpenSCAP or Lynis before and after.

  • On Windows, hardening means applying Microsoft's security baselines or the CIS Benchmark for your Windows Server version. Your typical work covers RDP behind a VPN with Network Level Authentication, unique local admin passwords, SMBv1 off, and Windows Defender Firewall rules. You add an audit policy that records logins and privilege changes, and IIS gets its own TLS and header settings.

  • You do it in small, tested batches with a snapshot before each one. Start with a benchmark scan, rank the failed checks, and group fixes by area. Apply one batch, test logins, the site, email, and scheduled jobs, then move on. Keep a log of each change and each check you leave open on purpose.

  • You get the before and after scores, a hardening log, and rollback notes, plus 30 days of support if a change affects your app. Settings drift over time, so the Hardening as Code plan adds a drift check. For monthly care, our Server Management Services can keep the baseline in place.
