Cyber Rebels — the free cybersecurity & privacy toolkit

Cyber Rebels is a free, browser-based cybersecurity and privacy toolkit for security analysts, students, and everyday people who want to understand and reduce their digital exposure. Everything runs in your browser with no account and no tracking — a lookup only leaves your device when a tool has to query a public threat-intelligence source on your behalf, and nothing is ever stored or sold. The site is organised into three clear sections so anyone can find their way around in seconds: interactive Tools, step-by-step Guides, and a Blog.

Tools

Browse the full tools directory. The flagship Threat Lookup correlates VirusTotal, AbuseIPDB and Shodan on any IP address, domain, URL or file hash and returns a single, plain-English verdict — including whether an address has a history of communicating with known malicious files, how many, and how recently. The Intel Radar streams the CISA Known Exploited Vulnerabilities catalogue alongside ransomware, dark-web and DDoS feeds. The Email & Phishing Analyzer breaks down message headers, SPF, DKIM and DMARC, extracts links and domains, and scores how likely a message is a phishing attempt. Domain Intel reports registration age, registrar, nameservers and DNS records with a risk score; the URL redirect analyzer unwinds shortened links to their real destination; the SSL certificate inspector reads a live TLS certificate; the QR code scanner decodes a QR image safely; and the decoder bench stacks Base64, Hex, URL, ROT13 and JWT operations.

What is my IP & privacy checks

Quick utilities answer the questions people search for most. What is my IP address? shows your public IP, your approximate city-level location on a live map, your internet provider and time zone, and explains in plain language what that address does and does not reveal — the fastest way to confirm whether a VPN is actually hiding your real address. The Privacy Center goes further: Am I Being Tracked? reports your IP, location, device and a live privacy score; the browser fingerprint test reveals the cookieless signals that follow you across the web and how rare your configuration is; and the Anti-Detect Lab lets you experiment with fingerprint profiles. You can also check whether your email addresses and passwords have appeared in known data breaches, and find the people-search data brokers selling your profile along with the links to opt out.

People, profiles & pen testing

For open-source intelligence on people and accounts, Username Search checks a single handle across dozens of platforms at once, the new Phone Number Search detects a number's country and hands you the best reverse-lookup and spam-report services, and the public footprint audit helps you see yourself the way an investigator would. The pen-test toolkit adds a passive subdomain scanner, an Nmap command builder, a hash identifier and a CIDR subnet calculator for testing you are authorised to perform.

VPNs & quantum

Choosing a VPN is hard because so many reviews are paid placements. Our VPN comparison rates each provider on an honest 0–100 trust score with the reasoning shown, weighting independently-audited no-logs policies and jurisdiction over commission. The Quantum-Safe VPN Tracker is a timely, sourced record of which providers have actually deployed NIST post-quantum encryption (ML-KEM) today, which are only laying groundwork, and which merely market it — every entry is dated and linked to a primary source, with an honest note that hybrid classical-plus-post-quantum designs are the credible signal.

Guides, blog & interactive labs

Sixteen plain-English guides walk you through accessing Tor safely, building strong passwords, hardening your browser and phone, spotting phishing, threat modelling and protecting yourself from doxxing. Hands-on interactive labs teach how password hashing and salting work, how attackers crack weak passwords, how IP addressing works and how network traffic flows across the internet. The blog covers timely topics in plain language, from browser fingerprinting and the data-broker economy to exactly where and how to report cybercrime to the FBI's IC3, CISA and the MS-ISAC.

Why it matters

You do not have to be a target to benefit. Every site you open quietly collects your IP, approximate location, device details and a fingerprint unique enough to recognise you again — usually with no login required. Cyber Rebels exists to make those invisible signals visible and to give you the same tools professionals use to investigate threats and shrink their own footprint, in language that actually makes sense. The tools are free, run entirely in your browser, store nothing, and never sell your data. Please enable JavaScript for the full interactive experience; the links above work without it.
