Run TestAUTOSECURITYAPP SECURITY CENTER
One Dashboard. Multiple Layers of Practical Protection.
AutoSecurityApp is designed around the security checks that a modern browser or PWA can legitimately perform. It does not claim that a web application can silently scan every installed app, inspect private application data or replace native operating-system antivirus.
Security Center areas:
Overview • Passwords • URLs & Phishing • Files • Privacy • Websites • Email Security •
Performance • Encrypted Vault • App Safety • Reports.
What AutoSecurityApp Can Actually Protect
🔐 Password & Account Security
Analyze password strength locally, generate strong passwords, optionally check breach exposure using k-anonymity and keep credentials in an AES-GCM encrypted local vault.
🛡 Web & Phishing Safety
Analyze suspicious URLs and message text, inspect website security headers and audit email-domain SPF, DMARC and DKIM records.
📁 User-Selected File Safety
Hash selected files with SHA-256 and inspect extensions, double extensions and executable signatures. Files are selected by the user and remain within browser permissions.
⚡ Safe Performance Diagnostics
Measure browser/device capabilities, storage, rendering, CPU and same-site latency without pretending to terminate arbitrary applications or rewrite operating-system settings.
◎ Privacy & Permissions
Review secure context status, WebCrypto, WebAuthn, privacy signals, browser storage and available permission states.
📲 Full PWA
Install AutoSecurityApp on supported phones, tablets, laptops and desktops with a standalone, offline-capable application shell.
Important: AutoSecurityApp is a browser/PWA security toolkit, not a kernel-level
antivirus. It cannot silently scan every application, intercept all network traffic, read other
applications' private files or replace native operating-system security software.
FULL CAPABILITY SET
Built from Safe, Practical Security Principles
The architecture adapts useful concepts from Omega Security Engine Pro and Omega Performance Engine into capabilities that are appropriate for a cross-device browser/PWA environment.
- Security scoring — Unified diagnostic scoring across browser security, passwords, URLs, user-selected files and performance health.
- Phishing & URL analysis — Structural checks for suspicious links, punycode, raw-IP hosts, disguised destinations and scam-language patterns.
- File integrity concepts — SHA-256 hashing and local inspection translate file-integrity concepts into user-granted file checks.
- Password security — Password strength, cryptographic generation, optional k-anonymity breach checks and an encrypted local credential vault.
- Website hardening audit — Public security-header inspection rather than rewriting server configuration or forcing risky settings.
- Email-domain protection — SPF, DMARC and DKIM DNS checks to help identify public domain-level email authentication gaps.
- Privacy & permissions — Secure context, WebCrypto, WebAuthn, privacy signals, permission states and browser storage information.
- Performance diagnostics — Safe-first benchmarks and capability reports rather than unsupported claims that a web app can clean the operating system or terminate arbitrary apps.
- Installable PWA — Standalone use across supported phones, tablets, laptops and desktops with an offline-capable application shell.
SECURITY MODEL
What It Does — and What It Deliberately Does Not Claim
Designed to Do
Local password tools • encrypted vault • phishing analysis • URL structure checks • user-selected file hashes and heuristics • browser/privacy audits • public website header audits • email-domain DNS audits • performance diagnostics • local reports.
Not Claimed
Kernel-level antivirus • full-device malware scanning • continuous network interception • silent scanning of other apps • reading private email accounts • accessing other apps' passwords • operating-system firewall replacement.
