Free OWASP Risk Assessment Calculator Evaluate technical cyber risks with precision. Analyze threats, vulnerabilities, and impact in real time to support audits, compliance, and mitigation strategies.
Use our OWASP Risk Assessment Calculator to perform in-depth cybersecurity evaluations based on threat agents, system vulnerabilities, and business impact. This tool enables security teams to quantify risks aligned with international frameworks like ISO 27005, NIST SP 800-30, and OWASP Top 10.
Ideal for internal security reviews, penetration testing documentation, and technical compliance audits.
Threat Agents Skill Level
(0) No technical skills – User with basic interaction only (1) Minimal knowledge (2) Basic system usage (3) Some technical skills – Basic understanding of systems (4) Moderate user with admin exposure (5) Advanced user – Confident with IT systems (6) Network & programming skills – Moderate attacker profile (7) Highly technical – Insider or dev role (8) Near-expert level (9) Security penetration skills – Highly skilled attacker Motive
(0) No interest or reward (1) Minimal incentive (2) Occasional interest (3) Possible reward – Motivated but uncertain benefit (4) Regular intent (5) Moderate personal gain (6) Frequent attempts expected (7) Highly motivated financially (8) Extremely persistent (9) High reward – Strongly motivated Opportunity
(0) Full access or expensive resources required – Very limited (1) Complex access path (2) Advanced access needed (3) Restricted credentials (4) Special access/resources needed – Limited exposure (5) Controlled access (6) Some access/resources – Medium exposure (7) Moderate exposure (8) Easy access possible (9) No access/resources – Anyone can attempt Size
(0) Very small group (1) Developers – Internal and trusted users (2) Team-level access (3) Intranet users – Employees or limited audience (4) Department-level users (5) Partners – External but known entities (6) Authenticated users – Broader access group (7) Large authenticated base (8) Unknown users (9) Anonymous users – Open access from web
Vulnerability Factors Ease of Discovery
(0) Practically impossible – No known method of discovery (1) Extremely difficult to detect (2) Requires deep knowledge (3) Difficult – Requires effort or knowledge (4) Moderate detection possible (5) Visible under certain conditions (6) Visible to power users (7) Easy – Documented or easy-to-find issue (8) Public exposure in forums (9) Automated tools – Public and easily exploitable Ease of Exploit
(0) Theoretical – Exploit not yet proven (1) Very hard to exploit (2) Rarely achievable (3) Difficult – Requires skill (4) Doable with some effort (5) Easy – Basic knowledge is enough (6) Script kiddie possible (7) Widely known technique (8) Exploit published online (9) Automated tools – Exploitable by anyone Awareness
(0) Unknown – Hidden from attackers (1) Not well-known (2) Obscure or internal only (3) Hidden – Known to few (4) Recognizable by researchers (5) Obvious – Easy to infer (6) Obvious to devs (7) Notorious within industry (8) Media coverage (9) Public – Known issue widely discussed Intrusion Detection
(0) Active detection in application (1) Advanced alerting system (2) Multiple audit trails (3) Logged & reviewed – Alerts and audits in place (4) Basic monitoring (5) Logs generated but not analyzed (6) Logs overwritten frequently (7) Logs stored but ignored (8) Logged only – No active monitoring (9) Not logged – No trace of attack
Impact Factors Loss of Confidentiality
(0) No data exposed (1) Minimal exposure – Harmless data (2) Small config leaks (3) Generic internal info leaked (4) Non-sensitive user data (5) Widespread user data exposure (6) Extensive non-sensitive data (7) Customer records leaked (8) All user records (9) Total breach – All data exposed Loss of Integrity
(0) Data untouched (1) Minor corruption – Non-critical impact (2) Temporary data issue (3) Local corruption in cache (4) Disruption in reports (5) Important but recoverable (6) Serious corruption – May affect operations (7) System-wide corruption (8) Widespread data loss (9) Severe corruption – System unusable Loss of Availability
(0) No service impact (1) Minor interruption – Limited services affected (2) Rare short outages (3) Temporary slowness (4) Periodic failures (5) Moderate unavailability (6) Major services affected – Noticeable downtime (7) Critical processes offline (8) System inaccessible (9) Total loss of service Financial Damage
(0) No cost (1) Negligible – Recovery cheaper than damage (2) Insignificant (3) Low direct cost (4) Moderate disruption (5) Temporary financial dip (6) Significant – May affect annual profit (7) Heavy fines or claims (8) Substantial loss (9) Severe – Threatens company survival Reputation Damage
(0) No impact (1) Reputation safe – No public visibility (2) Internal only (3) Partner notifications required (4) Loss of goodwill – Moderate media/partner impact (5) Customer concern (6) Moderate negative press (7) Public backlash (8) Media crisis (9) Brand damaged – Public trust severely impacted Risk Results Likelihood:
