Description
Before you open a website see its SUS or BUS rating and decide whether to continue SUS OR BUS — KNOW BEFORE YOU CLICK Every day you open dozens of websites: from search results, from links in emails and chat messages, from bookmarks, from pinned tabs. Most of them are fine. Some of them are traps — fake shops, phishing pages, scam downloads, sites that quietly hoover up your data. Sus or Bus is a browser extension that tells you which is which BEFORE the page loads, before you click anything, and before a scammer gets a single byte of your information. The idea is simple. Every website gets one of two verdicts: • BUS — the site looks safe and legitimate. Browse away. • SUS — the site shows warning signs. Think twice. No vague risk percentages. No impenetrable security jargon. Just the answer you actually came for: is this website sus, or is it bus? WHAT IS SUS OR BUS? Sus or Bus is a web safety checker that comes in two parts: this browser extension and the Sus or Bus website (susbus.base44.app), where you can analyze links, email text, HTML, code snippets, and uploaded documents in depth. The extension brings the same safety engine directly into your browsing. When you are about to open a website, it checks the site, shows you the verdict, the safety score, and the key findings in plain language — and then lets YOU decide whether to continue. • Click a link to another site on any webpage: the extension pauses for a moment and shows a compact rating card in the corner of your screen with Continue / Cancel. Same-site links and Ctrl/Cmd-clicks pass straight through, so normal browsing is never slowed down. • Open a site directly — from a pinned tab, a bookmark, your browser history, or by typing the address: the extension shows the full safety report full-screen before letting you browse it. Safe sites get one big green Proceed button. Suspicious sites get a deliberately smaller proceed button and an option to find safer alternatives instead. • Every rating is a link away from the full detailed report on the Sus or Bus website, with a technical breakdown for those who want to go deeper. THE VERDICT SYSTEM Sus or Bus deliberately avoids wishy-washy output. Instead of a color-coded "maybe," you get a binary answer: • BUS (safe): the site checks out. The verdict line reads "Valid." • SUS (suspicious): the site shows red flags. The verdict line reads "Not Valid." Alongside the verdict you get a 0–100 safety score, a plain-language summary of WHY the site got its rating, and up to four of the most important findings — good, warning, or bad — so you can see at a glance what is going on behind the scenes. The binary verdict is intentional: research on risk communication shows that people act on clear answers, not on "this site is 34% likely to be risky." A score of 0–100 is there for context, but the verdict is the headline — and it always matches: a BUS site reads Valid, a SUS site reads Not Valid. HOW IT WORKS: CHECKS BEFORE YOU CLICK 1. Click interception. When you click a link that leads to a different site, the extension intercepts the click before navigation happens. It looks up the destination, fetches its safety rating, and shows it to you in a small corner card. You can continue to the site, cancel, or open the full report. This works on links in emails you read in your browser, in forums, in social media, on news sites — anywhere a link to another website appears. 2. Full-screen takeover for direct visits. Many dangerous visits do not start with a link click. They start with a pinned tab you open every morning, a bookmark you saved long ago, or an address you typed after hearing about a "great deal." That is why Sus or Bus also covers direct navigation: when you open a site straight from a bookmark, pinned tab, history, or the address bar, the extension displays the site's full safety report full-screen before you browse it. You see the verdict, the score, and the findings — and you choose to proceed only when you are satisfied. Reloads and back/forward navigation are never interrupted, so once you have decided, browsing is completely smooth. 3. Cache plus auto-scan. Sites you have checked before show their rating instantly, because ratings are cached on your device for 7 days. New sites are scanned automatically in the background the moment you need a rating, which takes a few seconds the first time. Scanning happens on the Sus or Bus servers — your browsing is not slowed down while it runs, and nothing about you is attached to the result. FIND SAFER ALTERNATIVES When a site is rated SUS, the proceed button shrinks — going there should never be the easy option. In its place you get "Find alternative websites": one tap and Sus or Bus suggests well-known, reputable websites that serve the same purpose as the flagged site. If a shady outlet store is selling designer sunglasses at half price, the extension suggests the official brand store and established authorized retailers. If a download site looks suspicious, it points you to the official vendor page. Suggestions include the site name, the full URL, and a one-line reason why it is a safe alternative — and every suggestion is checked for legitimacy. This feature also lives on the Sus or Bus website: every SUS report for a website includes the same alternative finder. WHAT THE SAFETY ENGINE CHECKS Every scan looks at the actual content and behavior of the site, not just a URL string. The engine checks for classic phishing markers (login or payment forms on suspicious domains, requests for passwords or card details, urgent scare-tactic language), fake shop warning signs (unrealistic discounts, missing contact information, copied or nonsensical legal pages), tech-support and "you have a virus" scam patterns, crypto investment fraud signals, suspicious download patterns, misleading redirects, tracking technologies and what data the site collects, domain and brand impersonation (lookalike spellings of famous brands), the site's overall content quality and technical fingerprint, and much more. Good signs count too: real business information, professional content, sane checkout flows, and transparent privacy practices all push a site toward BUS. The result is not a black box. Each finding is written in plain language (with a more technical version available on the website for those who want it), so you can always see the reasoning behind the verdict — and disagree with it if you want to. REAL EXAMPLES OF HOW IT HELPS • The half-price deal. A friend messages you a link to a "flash sale" on designer sneakers, 70% off. You click it. Sus or Bus intercepts the click, runs the scan, and shows SUS with findings like "no verifiable business information" and "checkout page imitates a well-known brand." The proceed button is small; one tap on "Find alternative websites" shows the brand's official store and two trusted retailers instead. • The pinned tab. You keep a local news site pinned and open it every morning. One day the site's domain quietly changed hands after it was re-registered by a different owner. When you open the pinned tab, Sus or Bus covers the screen with the report before the new content runs — and you see what changed. • The email link. An email that looks like your bank asks you to "verify your account" through a link. You click it in your browser's webmail. The extension intercepts the click before the page loads and flags the destination — a lookalike domain with a login form. Not Valid. • The software download. You search for a popular free tool and click the first promising result. The scan finds the page serves installers from an unrelated domain and shows scare-tactic pop-ups. SUS — and the alternatives finder points you to the tool's official page. WHO IT IS FOR • Shoppers who want to know if an unfamiliar online store is real before entering card details. • Parents and grandparents who click links in emails and messages and need a safety net that speaks plainly. • Anyone who has ever asked "is this website legit?" about a deal, a download, a login page, or a strange link. • People who research health, finance, or legal topics and land on low-quality or misleading sites. • Anyone who wants a second opinion before opening a link from an unknown sender. • Teams and workplaces that want an extra guardrail against phishing-style traps. • Anyone who has been burned by a scam site once and does not want it to happen again. PRIVACY FIRST Sus or Bus is anonymous by design. There is no account, no sign-up, no login, and no profile. The extension does not read or store your personal information, does not track your browsing history beyond the 7-day rating cache described above, and does not sell or share data — there is nothing to sell. When a site is scanned, what is sent is the site address, so the servers can fetch and analyze the site's public content. The verdict comes back, gets cached on your device, and that is it. You can wipe all local data from the extension or the app's settings at any time. WHY ANOTHER SECURITY EXTENSION? Most security add-ons are built for the security industry: dashboards, threat levels, alert feeds. Sus or Bus is built for everyone else — the people who just want to know whether to click. It asks one question, gives one answer, explains itself in one screen, and never takes control of your browser away from you. It also goes where traditional tools do not: not just link clicks, but the sites you open on your own — bookmarks, pinned tabs, typed addresses — which is exactly where routine turns into risk. And when the answer is SUS, it does something genuinely useful instead of just saying no: it finds you a better place to get the same thing done. HOW TO INSTALL (about a minute) 1. Download the Sus or Bus extension folder to your computer. 2. Open a new tab and go to chrome://extensions. 3. Turn on Developer mode using the toggle in the top-right corner. 4. Click "Load unpacked" and select the downloaded sus-or-bus folder. 5. Done. Open any website directly or click any link to another site and watch the verdict appear. The extension works immediately — no configuration, no accounts, no setup steps. FULL REPORTS ON THE WEBSITE The extension is the fast lane; the Sus or Bus website is the deep dive. Every verdict links to a full report at susbus.base44.app with a score gauge, every finding in detail, the site's data collection and tracker profile, its detected technologies, a live preview of the site when possible, the recovered source code, simple and technical summaries, and export to PDF. The website also analyzes raw links, email contents, HTML, code, and uploaded documents — the same verdict system, for everything that is not a website you are about to open. FREQUENTLY ASKED QUESTIONS Q: Does it slow down my browsing? A: No. Ratings for sites you have already checked appear instantly from the local cache, and same-site navigation is never interrupted. Only first-time visits to a site need a few seconds for the automatic scan. Q: Does it block websites? A: No — you are always in control. Sus or Bus shows you the report and lets you decide. Nothing is censored, and every page can be opened with one tap if you choose to. Q: Is it free? A: Yes. The extension and the website are free to use. Q: Do I need an account? A: No. There is nothing to sign up for and nothing to log in to. Q: What does SUS actually mean? A: SUS (short for "suspicious," popularized by the game Among Us) means the site showed genuine warning signs — it does not necessarily mean the site is actively malicious, but it means you should not trust it with your data or money without a second look. Q: What does BUS mean? A: BUS is the opposite of SUS: the site looks safe, legitimate, and trustworthy. Final verdict: Valid. Q: Why show a full-screen report when I open a site directly? A: Because the most dangerous visits are often the ones you start yourself without thinking — a pinned tab, an old bookmark, an address from an ad or a message. The full-screen report is a single calm moment where you can see what you are about to open. If the site is safe, it is one tap to proceed. Q: What if I disagree with a verdict? A: Every finding is shown, so you can judge for yourself. The verdict is advice, not a verdict from a court. If you trust a site the extension rated SUS, you can proceed — the button is there, just deliberately not the biggest one on the screen. Q: How fresh are the ratings? A: Ratings are cached for 7 days per site, then re-scanned automatically the next time you visit. The full report on the website also has a rerun-scan button, so you can force a fresh check at any time. Q: How is this different from my browser's built-in warnings? A: Built-in warnings mostly cover already-known dangerous pages and certificate problems. Sus or Bus analyzes the site itself — its content, forms, claims, and structure — so it can catch brand-new scam pages that are not on anyone's blocklist yet. Q: What languages does it support? A: The Sus or Bus website speaks 16 languages with more being added. The extension currently keeps things simple in English. Q: Does it work in Safari, Firefox, or Edge? A: A Safari version is available — see the Sus or Bus website for the download and instructions. Other browsers are on the roadmap. Q: Will it work on my phone? A: The Sus or Bus website works great on mobile; browser extensions depend on what your mobile browser supports. Q: Can I suggest a feature or report a wrong verdict? A: Absolutely — contact us through the website at susbus.base44.app or email support@susorbus.com. TIPS FOR GETTING THE MOST OUT OF IT • Let first scans finish on important links — the wait is a few seconds and the answer lasts a week. • On a SUS site, always try "Find alternative websites" first; the extension suggests safe places that do the same job. • If a verdict surprises you, open the full report — every finding is explained in plain language, so you can see exactly what triggered it. • Share reports with family: every report has a link you can copy, so someone less technical can see the same explanation you saw. A FINAL WORD Security tools usually speak in colors and percentages that nobody outside a SOC team understands. Sus or Bus speaks human: sus, or bus. Behind that simple language is a serious engine that fetches the page, reads it, and explains what it found — every single time you are about to open a site you have never opened before. Install it once, and every future visit to an unknown website starts with an answer instead of a gamble. Note: Sus or Bus provides automated assessments for informational purposes. It does not guarantee that any website is safe or malicious, and it is not a substitute for your own judgment. Never enter passwords, card details, or personal information on a site you do not trust — even if a tool says it looks fine. Sus or Bus — know before you click.
