title: Security Ninja vs Solid Security 2026

Solid Security (formerly iThemes Security) and Security Ninja both harden WordPress. The philosophy differs. Solid Security is hardening-first: login and config controls, recommendations, and related protections. Security Ninja is an all-in-one Free-to-Pro stack: tests and vulns on Free, then Cloud Firewall, malware, login/2FA, and agency tools on Pro.

Products change. Verify current Solid Security plans on their site before you buy. This is a fit comparison, not a scorecard. Hub pages: [compare](https://wpsecurityninja.com/compare/) and [best WordPress security plugins](https://wpsecurityninja.com/best-wordpress-security-plugins/).

## Who each fits

**Security Ninja fits** site owners, freelancers, and agencies who want one plugin path for visibility and active protection. Free gives you 50+ security tests, vulnerability scanning, core integrity, events logging, and basic firewall rules. Pro adds the living protection layer without bolting on a second product.

**Solid Security fits** people who care most about checklist-style hardening and configuration hygiene: tighten login and config settings, follow recommendations, then decide whether malware or a cloud WAF still needs a separate tool.

If your site is already compromised, clean first. A comparison page is not incident response. See [malware removal](https://wpsecurityninja.com/wordpress-malware-removal/) or [consultation](https://wpsecurityninja.com/consultation/).

## Hardening-first vs Free-to-Pro all-in-one

That is the real fork.

**Hardening-first (Solid Security’s usual strength)**

- Run through security recommendations
- Lock down login and WordPress config habits
- Reduce noisy defaults and weak settings
- Decide later whether you still need scheduled malware scans or cloud IP blocking

**All-in-one Free-to-Pro (Security Ninja’s path)**

- Free: see gaps with [security tests](https://wpsecurityninja.com/security-tests/), [vulnerabilities](https://wpsecurityninja.com/vulnerabilities/), and [core integrity](https://wpsecurityninja.com/core-scanner/)
- Pro: block junk with [Cloud Firewall](https://wpsecurityninja.com/cloud-firewall/) (600M+ bad IPs, country/custom rules), scan on a [schedule](https://wpsecurityninja.com/scheduled-scanner/), harden login with [2FA](https://wpsecurityninja.com/two-factor-authentication-2fa/), add WooCommerce rate limits, webhooks, and white label / MainWP

Neither approach is “wrong.” Hardening without malware and firewall coverage leaves gaps. A firewall without config hygiene leaves avoidable doors open. The useful question is whether you want those jobs in one product or assembled deliberately.

## Job comparison

Confirm Solid Security’s current Free vs Pro matrix on their site. The table below is a buying lens.

| Job | Security Ninja | Solid Security (typical) |
| --- | --- | --- |
| Hardening / security tests | Free: 50+ actionable tests | Core strength: recommendations and config/login hardening |
| Vulnerabilities | Free: scanner for plugins, themes, core | Confirm current vuln coverage on their plans |
| Firewall / bad IPs | Free: basic rules. Pro: Cloud Firewall with living bad-IP intel | Hardening suite may include protections; confirm cloud IP / WAF depth |
| Malware scanning | Pro: malware scanner + schedules | Often lighter than malware-first tools; confirm or plan a companion |
| Login / 2FA | Pro: login protection + 2FA | Strong focus area historically; confirm Free vs Pro |
| Agency tooling | Pro: white label, MainWP, webhooks | Multi-site and agency options vary by plan; verify licensing |

## When Security Ninja wins

Choose Security Ninja when you want:

- Vulns, malware, and Cloud Firewall in the same Free-to-Pro product
- Continuous bad-IP blocking and country/custom rules without a second vendor
- Scheduled malware scans next to login hardening and 2FA
- Agency white label / MainWP and webhooks when client count grows
- An [install wizard](https://wpsecurityninja.com/install-wizard/) that aims for practical defaults, not a blank checklist

Typical workflow: install Free, run tests and the vuln scan, fix what you understand, upgrade to Pro when you want active blocking and scheduled malware without juggling tools.

## When Solid Security wins

Choose Solid Security when you want:

- Hardening and configuration hygiene as the main job
- A recommendation-driven workflow you already like from the iThemes era
- To add malware scanning or a cloud WAF deliberately later, instead of buying a full suite on day one
- Login and config controls as the center of the product, not one module among many

Typical workflow: walk hardening recommendations, tighten login/config, then audit whether malware and firewall coverage still need another layer.

## Watch-outs

**Full coverage may need more than hardening.** If Solid Security’s current plan is light on malware or cloud WAF, plan that gap on purpose. Do not assume “security plugin installed” means every job is done.

**Do not stack overlapping suites.** Login lockouts and firewalls from two products fight each other. One primary application stack. Optional companion: host or CDN edge WAF. Unwind messes with [plugin conflicts](https://wpsecurityninja.com/security-plugin-conflicts-resolution/).

**Verify Free vs Pro on both sides.** Vendors gate features differently. Security Ninja’s Free layer is visibility (tests, vulns, core, events, basic firewall). Pro unlocks Cloud Firewall, malware schedules, stronger login/2FA, Woo tools, and agency options. Solid Security’s split may look different. Read both matrices.

**Products rename and rebundle.** Solid Security used to be iThemes Security. Feature pages and pricing pages are the source of truth, not old blog posts.

## How to choose quickly

1. Is your priority “fix weak defaults” or “one stack for vulns + firewall + malware + login”?
2. Will you maintain a second tool for malware or WAF if hardening alone is not enough?
3. Do you need agency white label / MainWP now, or later?
4. Does your host already provide a strong edge WAF?
5. Which product will you finish configuring this week?

Stores should also weigh checkout and coupon abuse controls. Security Ninja Pro includes WooCommerce rate limits. See [WooCommerce security](https://wpsecurityninja.com/woocommerce-security-guide/).

## Bottom line
