Hardenize Alternative for Agencies and Freelance Developers
Hardenize moved to enterprise-only pricing ($5K+/year) after its acquisition by Red Sift. Here's what changed, who's affected, and how to monitor your sites' security posture without an enterprise contract.
If you’ve been using Hardenize to track the security configuration of your sites, you’ve noticed the self-serve tier is gone. After Red Sift acquired Hardenize, the product moved upmarket — pricing now starts at $5,000/year and is aimed squarely at enterprise security teams.
That’s a reasonable direction for a business. It’s also a dead end for web agencies and freelance developers who were using Hardenize to track security posture across a handful of client sites.
This post covers what Hardenize did, what’s changed and what continuous security monitoring looks like for teams that don’t have an enterprise budget.

What Hardenize did well
Hardenize was genuinely useful. It combined certificate monitoring, email security checks (SPF, DKIM, DMARC), security headers, TLS configuration and network exposure into a single dashboard. For agencies managing a portfolio of client sites, having all of that in one place was the point.
The grading was trustworthy. The checks were comprehensive and critically it had a self-serve tier that made it accessible without procurement, contract negotiations or a security team budget.
What changed after the Red Sift acquisition
Red Sift acquired Hardenize in 2022. Over the following years, the product was absorbed into Red Sift’s broader enterprise platform and repriced accordingly. The self-serve option is gone. Current pricing starts at $5,000/year, positioned for enterprise security teams with formal procurement processes.
If you were on the self-serve tier, that access has ended. If you’re looking for an equivalent that doesn’t require a five-figure annual contract, you’re starting from scratch.
Who this actually affects
Enterprise security teams probably landed somewhere within the Red Sift ecosystem. This post isn’t for them.
This is for:
Web agencies managing security posture across 10–100+ client sites. You need to know when a client’s HSTS header disappears after a deployment, when a certificate is 7 days from expiry, or when a misconfigured CSP is dropping your client’s security grade. You need that across all your sites, with alerts, without manually running spot checks.
Freelance developers who added Hardenize to their stack because it caught the misconfigurations that their clients’ IT teams wouldn’t catch until after something broke. You’re not buying a $5K/year enterprise tool. You need something that works, costs what a SaaS tool should cost and stays out of your way.
DevOps engineers at SMBs who care about security posture but don’t have a dedicated security team. You want continuous monitoring, not a quarterly manual audit.
What security posture monitoring should cover
Hardenize’s breadth was one of its strengths. A replacement should cover the same ground:
TLS and certificate expiry Your certificates, tracked automatically. Alerts at 30 days and 7 days before expiry. A surprise SSL expiry takes a site offline and destroys user trust — it’s one of the most avoidable incidents in web operations.
Security headers CSP (Content-Security-Policy), HSTS (Strict-Transport-Security), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. Missing or misconfigured headers should trigger an alert when they change — not when you happen to run a manual check.
DNS security DNSSEC validation and CAA record presence. Missing DNS security records are a common oversight that leaves domains exposed to hijacking.
Cookie security
Cookies missing Secure, HttpOnly, or SameSite attributes are a frequent finding on sites that have grown organically without a systematic security review.
Exposure paths
Common sensitive paths probed for accidental exposure: /.git/, /.env, /phpinfo.php, /wp-login.php, /adminer.php. An exposed .git directory can leak your entire source code — and it’s more common than most developers expect.
Guardr also scans live JavaScript bundles for exposed API keys (OpenAI, Stripe, AWS, Anthropic, Google AI, Supabase) — checking what’s deployed in production, not just your repository.
Uptime Availability checks every 1–5 minutes, with alerts. Security and uptime belong in the same dashboard — both affect your users, both need immediate alerts when something changes.
How Guardr compares
| Hardenize | Guardr | |
|---|---|---|
| Continuous security monitoring | ✅ | ✅ |
| Security header checks | ✅ | ✅ |
| Letter grade (A–F) | ✅ | ✅ |
| TLS / certificate expiry alerts | ✅ | ✅ 30d and 7d |
| DNS security (DNSSEC/CAA) | ✅ | ✅ |
| Cookie security checks | ✅ | ✅ |
| Exposure path detection | ✅ | ✅ |
| JS secret scanning | ❌ | ✅ (live bundles) |
| Uptime monitoring | ❌ | ✅ |
| Fix instructions per platform | ❌ | ✅ Cloudflare, Nginx, Apache |
| Scan history and trends | ✅ | ✅ |
| API access | ✅ (enterprise) | ✅ Paid plans |
| Self-serve tier available | ⛔ Gone | ✅ |
| Free scanner | ✅ | ✅ |
| Paid monitoring | ⛔ $5K+/year | ✅ From $7/month |
The practical gap for agencies and freelancers: Hardenize is no longer an option at a price that makes sense. Guardr covers the same monitoring surface — security headers, TLS, DNS, cookies, exposure paths — plus uptime, without an enterprise contract.
Grading methodology
Like Hardenize, Guardr assigns a letter grade (A–F) based on the overall security configuration of your site. The scoring covers a broader surface than headers alone:
- TLS / HSTS: 28%
- Security headers: 28%
- Exposure paths: 20%
- Cookie security: 14%
- DNS security: 10%
Your grade is tracked over time. If a deployment causes it to drop — a missing CSP after a framework update, HSTS accidentally stripped — you’ll see the change in your history and receive an alert before a client does.
Fix instructions — from finding to fix in one tab
Every failing check in Guardr includes platform-specific remediation. Not just “your CSP header is missing” — but the exact configuration snippet for Cloudflare Workers, Nginx, or Apache, ready to copy and deploy.
For example, a missing HSTS finding shows you exactly what to add to your _headers file on Cloudflare Pages, your server block on Nginx, or your VirtualHost on Apache.
The goal is to close the loop between finding and fix without opening a second browser tab. Hardenize surfaced the issue. Guardr surfaces the issue and hands you the fix.
Free scanner, no login required
Not ready to sign up? Scan any URL instantly at guardr.io — no account, no credit card. You’ll get a letter grade, a breakdown of every finding, and fix instructions for each misconfiguration.
The difference from a one-time scanner: after you see your results, you can start monitoring that URL automatically with one click. No manual rechecks, no forgetting to come back — your security grade stays current without any extra effort.
If you’re managing multiple client sites and need continuous monitoring across all of them, Guardr’s paid plans start at $7/month.
If you were a Hardenize self-serve user looking for a direct alternative, guardr.io covers the same ground — security posture monitoring across headers, TLS, DNS, cookies, and exposure paths — without the enterprise contract.
