About this service
We shut down brute-force noise on Australian login pages and leave you with authentication that is harder to abuse without breaking real users. Ideal when staff logins, customer portals, or booking forms keep getting hammered overnight and your team is tired of CAPTCHA whack-a-mole.
What You'll Get
- Attack pattern review - We map failed-login sources, timing, and endpoints so fixes target real abuse, not guesswork.
- Rate limiting & lockout design - Sensible thresholds that stop spray attacks while keeping support desks and shift workers productive.
- Login page hardening - CSRF, secure cookies, session fixation controls, and safer password reset flows.
- Fail2ban / WAF / edge rules - Practical ban lists and challenge rules tuned to your stack.
- MFA readiness path - Clear options for TOTP/app or hardware keys without forcing a full product rebuild on day one.
- Plain-English runbook - What changed, how to monitor, and when to escalate—written for ops and owners, not only developers.
Serving Australia & surrounds
Australian businesses mix public storefronts with back-office logins that sit open on the same domain—café POS portals, clinic patient forms, freight booking dashboards, and strata committee sites. Attack traffic often ramps outside business hours when no one is watching the auth logs. We work remote-first across metro and regional clients and keep guidance grounded in how Aussie teams actually operate.
- High-street and strip retailers with shared Wi‑Fi staff logins that get credential-stuffed after close
- Warehouse and industrial precinct booking portals hit during freight peaks and long weekend quiet hours
- Fully remote delivery with optional guided screen-share; on-site only if your policy requires a supervised change window
How We Work
- Step 1: Reach Out - Tell us the stack (WordPress, custom app, cPanel, cloud LB), symptoms, and whether customers or staff are locked out. We listen first.
- Step 2: Tailored Plan - Fixed-scope quote for diagnostics plus hardening; clear path if human walkthrough for your admin team is needed.
- Step 3: We Deliver - Remote configuration, rule sets, and login UX safety checks—patient explanation when non-technical owners need it.
- Step 4: Confirm & Follow-up - Verify reduced failure noise, hand over monitoring tips, and optional follow-up window for edge cases.
Common Issues & How to Fix Them
These are patterns we see repeatedly on Australian production logins—symptoms first, then safe checks you can run before escalating.
Nightly 401/403 spikes with the same username list
Credential stuffing often reuses leaked email lists against your staff or customer login; volume looks like real users until you graph failures by IP and user-agent.
- Step 1: Export the last 24–48 hours of failed auth and sort by username frequency and source IP—note any pure dictionary patterns.
- Step 2: Enable progressive delays or temporary lockouts after N failures per IP and per account; block known bad ASN ranges at the edge if your host allows.
- Step 3: Confirm success by watching failure rate drop while genuine logins still complete under three attempts without CAPTCHA storms.
XML-RPC or legacy wp-login hammering on WordPress
Bots still probe xmlrpc.php and wp-login.php in parallel; shared hosting CPU climbs even when the front page looks fine.
- Step 1: Check access logs for POST volume to xmlrpc.php and wp-login.php; note if REST routes also show auth spam.
- Step 2: Disable or tightly restrict XML-RPC if unused; force HTTPS-only admin, limit login to known paths, and add server-level rate limits or Fail2ban jails.
- Step 3: Verify with a controlled failed-login test from a clean IP and a second test from a blocked pattern—only the abuser path should trip bans.
Legitimate staff locked out after aggressive global CAPTCHA
Blanket CAPTCHA after any failure punishes shared office NATs and mobile carriers common across Australian CBDs and regional towns.
- Step 1: Identify whether lockouts correlate with carrier NATs or office egress IPs rather than single hostile hosts.
- Step 2: Move from global CAPTCHA to per-IP + per-account scoring, allowlist trusted office egress where appropriate, and prefer MFA over endless puzzles.
- Step 3: Have two staff on different networks sign in during peak; success means no false lockouts and still blocked scripted sprays in logs.

Expert Insights
On Australian retail and booking sites, the tell is rarely a single loud IP—it is a low-and-slow spray from residential and cloud ranges that never trips a simple “100 failures in 60 seconds” rule. After years of cleaning these up, we set dual windows: a short burst threshold for obvious bots and a longer rolling window that catches the same username tried once every few minutes from rotating sources. Pair that with denying auth on secondary endpoints (old APIs, XML-RPC, leftover staging hosts) before you tighten the main form. Good looks like failed-login charts flattening overnight while Monday morning staff logins stay uneventful; bad looks like a national CAPTCHA wall that locks half the office on a shared NBN egress while bots simply switch paths.

FAQ
Yes—we deliver primarily remote across Australia for login hardening and brute-force mitigation. Most changes are safer and faster over secure remote access with a change window you approve. On-site is uncommon for this work and only considered if your security policy requires supervised physical access.
That is exactly what we design against. We use graduated limits, careful allowlisting for known office egress where needed, and verification tests so genuine users keep working while scripted sprays get slowed or banned. You get a clear rollback note before risky switches.
Typically read access to auth/access logs and a staging or maintenance window for config changes—plus admin access to the host, panel, or WAF you want us to tune. We never require marketplace middle layers; you work directly with us and we document every change.
No. WordPress is common, but we also harden custom app logins, reverse-proxy front doors, and panel-level controls. Tell us your stack in the first message and we scope the fixed package accordingly.
