What Is a Security Credit Score and How Does ARK Calculate Yours
A security credit score is a 0-100 rating that measures how exposed your phone is to breach risk, malware, weak permissions, and network threats. ARK by MRVL gives you that score instantly, then shows exactly which vulnerabilities to fix.
How a Security Credit Score Works
Unlike a financial credit score, which predicts lending risk, a security credit score predicts cyber risk. It scans your device for four things: how permissive your apps are, whether your phone has been linked to known data breaches, whether your network connection leaks data, and whether stalkerware or spyware is installed. Each factor lowers or raises your score. ARK by MRVL calculates your score by running targeted scans across device security, network exposure, app permissions, and breach exposure. Every threat it finds comes with a one-tap fix, so you're not left wondering what to do next.
What ARK's Security Score Includes
ARK starts with a free scan that checks app permissions (how much access each app has to your contacts, location, camera) and looks for stalkerware. The free tier gives you a baseline score at no cost. If you upgrade to Shield (£2.99 per month or £29.99 per year), ARK adds breach history via Have I Been Pwned, dark-web monitoring to check if your email is for sale, a phishing scanner for URLs and QR codes, Wi-Fi security analysis, password health audit, and DNS leak detection. The top tier, Fortress (£7.99 per month or £79.99 per year), layers on data-broker exposure, automated GDPR data requests, AI-powered opt-out decisions, and voice-clone risk detection. Your score updates as you fix issues.
Why Your Security Score Matters
Your score is a shorthand for how likely you are to fall victim to identity theft, account takeover, or phishing. A low score doesn't mean you've already been hacked; it means your defences are weak. People who've experienced data breaches, privacy-conscious users, parents monitoring family devices, and small business owners often watch their score closely because one breach can affect multiple people. ARK's on-device scans (when possible) mean your results stay private. No analytics, no tracking, no selling your data to third parties on the free tier.
ARK Is Not an Antivirus or VPN
It's important to note what ARK doesn't do. It is not an antivirus scanner, so it won't remove malware. It is not a VPN, so it won't hide your IP address or encrypt all your traffic. It is not a password manager, so it doesn't store your passwords. What ARK does is expose where your defences are weak, then give you actionable fixes. If your score is low because you've been in a breach, ARK tells you which service leaked your data and advises you to change your password there. If it's low because an app has excessive permissions, ARK links you straight to settings to revoke them.
How to Read Your ARK Score
When you open ARK and run a scan, you'll see a single number from 0 to 100, plus a breakdown by category. Each category shows which specific issues are dragging your score down. For example, you might see 'Breach Exposure: 15 accounts found' or 'App Permissions: 8 apps with camera access'. Tapping any issue gives you a one-tap deep-link to fix it directly. The score recalculates after you make changes, so you see immediate progress. Over time, maintaining a higher score means fewer attack vectors for scammers or thieves to exploit.
Who Uses Security Scores
ARK is built for privacy-conscious adults aged 25-45 who want clarity on their phone's safety. Parents use it to audit their children's devices. Small business owners use it to check whether team phones are secure enough to handle sensitive data. Anyone who's been notified of a data breach finds ARK's breach monitor especially useful because it tells them which passwords to change first. As of June 2026, the trend toward personal cyber hygiene is growing; more users are checking their own security scores the way they once checked credit scores, especially after major breaches make news headlines.

Frequently asked questions
Is a security credit score the same as a financial credit score?
No. A financial credit score predicts your lending risk; a security credit score predicts your cyber risk. ARK's score is based on breach history, app permissions, network exposure, and threats like stalkerware.
Can ARK remove malware from my phone?
No. ARK is not an antivirus. It detects stalkerware and alerts you to threats, but it doesn't remove them. For actual malware removal, you'll need your phone's built-in security tools or a dedicated antivirus app.
Does ARK sell my data?
No. ARK is privacy-first. On the free tier, no analytics are collected. Your data stays on your device using iOS SecureStore or Android EncryptedSharedPreferences. Shield and Fortress tiers use encrypted storage for features like dark-web monitoring.
Why is my security score low?
ARK breaks down the reasons by category. Common causes are apps with excessive permissions, your email appearing in a known data breach, or a weak Wi-Fi connection. Each issue comes with a one-tap fix.
What does Shield tier add to my score?
Shield adds breach history via Have I Been Pwned, dark-web monitoring, phishing scanner, Wi-Fi analyser, password health check, and DNS leak test. These provide deeper insight into your exposure.
Is ARK available on Android?
ARK is currently available on iOS. Check the app store for the latest platform availability.
