Hi there, I understand your web server is under an active DDoS causing hundreds of IPs to attempt logins and service outage; I’ll stop the immediate attack and harden the server so it resists future floods. I have 7+ years securing Linux web stacks, firewall tuning and automated mitigations , I’ve handled live DDoS incidents with minimal downtime. - Immediate actions: deploy ipset + iptables/ nftables blocks, enable fail2ban with custom login filters, and implement rate-limiting at Nginx/Apache to stop login floods. - Network/edge mitigation: configure Cloudflare (or similar CDN/WAF) in “Under Attack” mode, set strict WAF rules, and enable IP reputation/blocklists. - Longer-term hardening: set up SYN/connection limits, tcp-proxy protections, automated blacklists, and monitoring + alerting (fail2ban + Zabbix/Cloudflare logs). - Risk & validation: staged deploy with traffic validation, rollback plan, and brief windowed maintenance to ensure minimal downtime and no false-positive lockouts. Skills: ✅ Network Security ✅ Web server security (Nginx/Apache) ✅ rate limiting & fail2ban automation ✅ Cloudflare/CDN + edge WAF deployment ✅ Firewall hardening (iptables/nftables) & connection limiting Certificates: ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ cPanel® & WHM Certified CWSA-2 I’m available now to start emergency mitigation. Do you have Cloudflare (or another CDN/WAF) available to place in front of the server now, and can you share SSH access or a control-panel for emergency ch

You're facing a DDoS-driven login flood that risks downtime and revenue. This is my speciality-protecting platforms from DDoS and login abuse, so your service stays online. I'm Iosif Peterfi, 15+ years helping PMs tighten security and resilience for web platforms. My approach focuses on outcomes, not jargon. I will implement a multi-layer plan: hardening the delivery surface, establish traffic controls, apply rate limiting on login attempts, and set up automated IP blocking for malicious activity. I will configure clear alerts, a lightweight protection tier for critical hours, and a simple playbook to recover fast after a spike. You'll gain a more predictable platform, reduced downtime risk, and faster, safer user access. Last month I helped an online retailer stop a bot-driven login flood; after implementing rate limits and IP filtering, downtime ended quickly and onboarding times improved by 30%. Let's chat - I can walk you through my approach in 15 minutes. Portfolio: https://www.freelancer.com/u/iosifpeterfi

@RomanSattar

Hi There! I can quickly stabilize your server and implement proper DDoS mitigation to stop the login flood and prevent further outages. I’ll analyze incoming traffic, block malicious IP ranges, implement rate limiting, firewall rules, and connection filtering, and configure stronger protection at the web server and network level. If needed, I can also integrate protection through services like Cloudflare to absorb and filter attack traffic before it reaches your server. The initial containment and mitigation typically takes 1–2 hours, depending on the server setup, after which I’ll apply longer-term hardening measures to keep the system stable under similar attacks. Best Regards, Roman S.

@letscms

Hello Sir, I can quickly resolve your current DDoS attack and secure your server with a robust, multi-layer protection approach. With 12+ years of experience, I’ve handled similar attacks involving heavy bot traffic and login floods. I will immediately stabilize your server, block malicious IPs, and implement rate limiting, firewall rules, and Fail2Ban to stop ongoing abuse. I’ll also secure your login endpoints with CAPTCHA and request throttling to prevent brute-force attempts. Additionally, I will integrate Cloudflare for advanced WAF, bot filtering, and DDoS mitigation, ensuring long-term protection. Server-level optimizations (Nginx/Apache tuning, connection limits) will also be applied. Timeline: Immediate mitigation: 1–2 hours Full protection setup: 6–12 hours You’ll get a stable, secure system that stays online even under attack. Let’s fix this before it impacts your users further. Best regards, Jitendra Sharma

@usamae

I've dealt with this exact scenario multiple times - brute force login attacks flooding the server. Here's what I'd do: First, immediate mitigation - fail2ban to auto-block IPs after failed login attempts, rate limiting at the nginx/apache level, and geo-blocking if the attack IPs are from specific regions. Then for longer term protection, setting up Cloudflare or similar WAF in front of your server, hardening SSH (key-only auth, non-standard port), and configuring proper iptables rules. Can usually get a server stable again within a few hours. Happy to jump on this today if its urgent. - Usama

@FizzaNadeemK

It sounds like your server is being overwhelmed by login flood attempts, which is a common pattern in DDoS and brute-force combinations. I would start by immediately stabilizing the server using firewall rules, rate limiting, and blocking abusive IP ranges to stop the downtime. Then I’d implement longer-term protection using tools like fail2ban, reverse proxy filtering (Cloudflare or similar), and strict login throttling. I’ll also review server logs to identify attack patterns and ensure legitimate users are not impacted. If needed, I can harden your web server configuration and close any exposed endpoints contributing to the issue. This can usually be contained within a few hours, with full protection and monitoring in place within 24 hours. I’ve handled similar live attacks before, so I understand the urgency and how to act without breaking your site. Can you share your server stack and whether you’re already using any CDN or firewall layer?
