Best Alternatives to Sigil for WordPress Login Security

Sigil takes a narrow, deliberate approach to WordPress login security: passkeys, TOTP, backup codes, and email codes, plus role-based enforcement and REST API routes for headless setups — and nothing else. That focus is the point, but it also means Sigil won't touch file integrity scanning, malware detection, firewall rules, or backups. If you're looking for a plugin that folds login protection into a wider security toolkit, or you want backups and scanning handled without adding yet another plugin to your stack, the alternatives below take a broader-suite approach instead of Sigil's single-purpose one.

PW Security and Backup bundles four things into one free plugin: login attempt limiting, file integrity scanning, malicious code detection, and automated ZIP backups of your site and database — all run from a single wp-admin settings screen with no companion app, no cloud dashboard, and no telemetry sent to a vendor. Backups are written as ZIP archives to a protected directory on your own server, and security logs stay local too, which makes it a fit for freelancers on tight budgets, agencies with data residency concerns, or self-hosters who already have off-site backup infrastructure and just want a fast local restore point. It won't give you a real web application firewall with threat-intelligence rule updates, and it doesn't push backups off-server to Dropbox, S3, or Google Drive natively — everything stays on the same box. There's no premium tier or licensing at all right now, just the free plugin.

Owl Security covers brute-force login protection, a malware scanner, firewall rules, two-factor authentication, and an activity log, with checks running locally on your server by default rather than phoning home to a vendor's cloud. Optional integrations with WPScan and Google reCAPTCHA are available but not required to use the plugin. This makes it a reasonable pick if you want 2FA bundled alongside broader hardening features in one lean plugin, particularly for freelancers managing several client sites, agencies with data-residency requirements, or shared-hosting sites that want to avoid a scanner leaning on external API calls. It's a weaker fit for larger e-commerce or high-traffic stores needing a managed WAF at the network/CDN edge, since Owl Security's firewall operates at the application layer only. The core plugin is free with no license key or forced account creation, and as of now there's no published premium tier.

Defen.so Connector runs its core protections — a local web application firewall, malware scanning, file integrity monitoring, and a hardening toolkit — entirely on your own server for free, with no account required. Everything runs locally, meaning no DNS changes and no routing your traffic through a third-party proxy. If you want capabilities that have to live outside your server, like external uptime monitoring, SSL expiry alerts, a mobile push-notification app, or a centralized dashboard for managing multiple sites, you connect a free Defen.so account for those add-ons, with a paid tier available for faster check intervals and more headroom. This is the closest of the three to a security-suite model that only charges for infrastructure it has to host itself, keeping the on-server protections free indefinitely.

All three of these alternatives trade Sigil's single-purpose focus for a broader bundle of protections — login hardening, malware scanning, backups, or firewalling — under one roof. If dedicated passkey and 2FA support with role-based enforcement and REST API access is all you need, Sigil still does that specific job without any extra surface area. But if you'd rather consolidate backups, scanning, and firewalling alongside your login protection, PW Security and Backup, Owl Security, or Defen.so Connector each offer a different balance of local-only processing versus optional cloud-connected extras.
