Vulnora works by sending automated security tests to your website URL. It checks for 60+ vulnerability types, analyzes responses, and generates a detailed report with findings, severity ratings, and fix recommendations.

A website vulnerability scanner is a cybersecurity tool that automatically tests websites for security weaknesses like SQL injection, cross-site scripting (XSS), misconfigurations, exposed secrets, and other vulnerabilities that hackers could exploit to steal data or compromise systems.

SQL injection is a web security vulnerability that allows attackers to interfere with database queries. By inserting malicious SQL code into input fields, attackers can read, modify, or delete database data. Vulnora detects error-based, blind, and time-based SQL injection.

XSS is a vulnerability where attackers inject malicious scripts into web pages viewed by other users. This can steal cookies, session tokens, or redirect users to malicious sites. Vulnora detects reflected, stored, and DOM-based XSS.

CORS (Cross-Origin Resource Sharing) misconfiguration occurs when a website allows requests from unauthorized origins. This can let attackers steal data from authenticated users. Vulnora checks for overly permissive CORS policies.

CSRF (Cross-Site Request Forgery) tricks authenticated users into performing unwanted actions on a website. Attackers craft malicious requests that execute with the victim's credentials. Vulnora checks for missing or weak CSRF tokens.

SSL/TLS encrypts data between browsers and servers. Without it, passwords and data are sent in plain text. Vulnora checks certificate validity, expiration, cipher strength, and protocol versions (TLS 1.0-1.3).

Security headers are HTTP response headers that protect against attacks. Key headers include Content-Security-Policy (CSP), Strict-Transport-Security (HSTS), X-Frame-Options, and X-Content-Type-Options. Vulnora audits all critical security headers.

Penetration testing (pen testing) is the practice of testing a system for vulnerabilities by simulating attacks. Vulnora performs automated penetration testing including injection attacks, brute force, authentication bypass, and more.

The OWASP Top 10 is a list of the most critical web application security risks published by the Open Web Application Security Project. It includes injection, broken authentication, sensitive data exposure, XXE, broken access control, security misconfiguration, XSS, insecure deserialization, using components with known vulnerabilities, and insufficient logging. Vulnora covers all 10 categories.

A port scan checks which network ports are open on a server. Open ports reveal running services (databases, admin panels, etc.) that could be attacked. Vulnora's Deep Scan agent scans 42 common TCP ports.

Subdomain takeover occurs when a DNS record points to an unclaimed external service (like GitHub Pages or Heroku). Attackers can claim that service and serve malicious content on your subdomain. Vulnora checks 100+ subdomains for takeover vulnerabilities.

A brute force attack tries many password combinations to gain unauthorized access. Vulnora tests login pages for rate limiting and brute force protection to ensure your site blocks repeated failed attempts.

Server-Side Request Forgery (SSRF) tricks a server into making requests to internal resources. Attackers can access cloud metadata, internal APIs, or other restricted services. Vulnora tests for SSRF vulnerabilities.

Insecure Direct Object Reference (IDOR) occurs when an application exposes internal objects (like database IDs) without proper authorization checks. Attackers can access other users' data by changing the ID. Vulnora tests for IDOR.

XML External Entity (XXE) injection exploits XML parsers to read server files, perform SSRF, or cause denial of service. Vulnora tests XML endpoints for XXE vulnerabilities.

Prototype pollution is a JavaScript vulnerability where attackers modify Object.prototype to inject properties into all objects. This can lead to XSS, denial of service, or remote code execution. Vulnora tests for __proto__ and constructor injection.

Command injection allows attackers to execute operating system commands on the server by injecting shell metacharacters into input fields. Vulnora tests for OS command injection in parameters and form inputs.

Path traversal (directory traversal) uses ../ sequences to access files outside the web root directory. Attackers can read sensitive configuration files, source code, or system files. Vulnora tests for path traversal attacks.

Clickjacking tricks users into clicking hidden elements by overlaying transparent frames on legitimate pages. Vulnora checks for X-Frame-Options and CSP frame-ancestors headers that prevent clickjacking.

Session fixation forces a user to use a known session ID. After the user logs in, the attacker uses the same session to access their account. Vulnora tests if session IDs are regenerated after authentication.

JWT (JSON Web Token) attacks exploit weaknesses in token implementation. Common attacks include algorithm confusion (alg:none), weak signing keys, and token manipulation. Vulnora tests for JWT vulnerabilities.

NoSQL injection targets databases like MongoDB using operator-based payloads ($gt, $ne, $regex) instead of SQL syntax. Vulnora tests query parameters for NoSQL injection patterns.

Server-Side Template Injection occurs when user input is embedded in template engines (Jinja2, Twig, Freemarker). Attackers can execute arbitrary code on the server. Vulnora tests for SSTI in multiple template engines.

File inclusion vulnerabilities (LFI/RFI) allow attackers to include files from the server (Local File Inclusion) or remote servers (Remote File Inclusion). This can expose source code or execute malicious files. Vulnora tests for both LFI and RFI.

Distributed Denial of Service (DDoS) floods a server with traffic to make it unavailable. Vulnora's Deep Scan agent tests your server's resilience by sending concurrent requests and measuring response degradation.

Malware scanning checks websites for malicious code, hidden iframes, cryptocurrency miners, SEO spam, and obfuscated scripts injected by attackers. Vulnora scans page source for known malware signatures.

A security audit is a systematic evaluation of a system's security posture. It identifies vulnerabilities, misconfigurations, and compliance gaps. Vulnora automates security audits with 60+ comprehensive checks.

Vulnerability assessment is the process of identifying, quantifying, and prioritizing security weaknesses in a system. Vulnora performs automated vulnerability assessment and ranks findings by severity (critical, high, medium, low, info).

Ethical hacking (white hat hacking) is authorized security testing to find vulnerabilities before malicious hackers do. Vulnora provides automated ethical hacking tools that test for real-world attack vectors.

A WAF protects web applications by filtering malicious HTTP traffic. Vulnora can detect if a WAF is present and test if it properly blocks common attack payloads.

CSP is a security header that controls which resources a page can load. It prevents XSS by blocking inline scripts and unauthorized sources. Vulnora analyzes CSP headers for misconfigurations and missing directives.

HTTP Strict Transport Security (HSTS) forces browsers to only use HTTPS connections. Without HSTS, attackers can downgrade connections to HTTP and intercept data. Vulnora checks for HSTS header presence and configuration.

A zero-day vulnerability is a security flaw unknown to the software vendor with no available patch. While Vulnora can't detect unknown zero-days, it identifies known vulnerabilities and misconfigurations that are commonly exploited.

Social engineering manipulates people into revealing confidential information. While Vulnora focuses on technical vulnerabilities, it checks for information disclosure that could aid social engineering attacks.

Phishing uses fake websites or emails to steal credentials. Vulnora helps prevent phishing by checking for subdomain takeover vulnerabilities and ensuring proper email security (SPF, DKIM, DMARC).

Ransomware encrypts files and demands payment for decryption. Vulnora helps prevent ransomware by identifying vulnerabilities that attackers use as entry points — exposed services, weak authentication, and unpatched software.

Data breach prevention involves securing systems against unauthorized access. Vulnora identifies vulnerabilities that could lead to data breaches: SQL injection, exposed databases, weak authentication, and information disclosure.

API security protects application programming interfaces from attacks. Vulnora tests APIs for authentication bypass, rate limiting, parameter tampering, injection attacks, and improper error handling.
