What "threat model" means, in plain English
A threat model is just an honest answer to three questions: what are you trying to protect, who are you trying to protect it from, and what happens if you fail? Security and privacy people use the term "threat modeling" for this, but the idea is ordinary — it's the same reasoning you use when you lock your front door but don't install a bank vault, or when you're careful with your passwords but don't encrypt every text message you send.
Most privacy tools and guides — including the ones on this site — are written for a specific level of risk. Applied to the wrong situation, they can either leave you under-protected (a casual user ignoring a real leak) or waste your time over-protecting against a threat that was never realistic for you (spending hours hardening a browser against a nation-state adversary you'll never face).
Three levels of privacy needs
These aren't official categories — they're a simple way to sort where you probably fall. Most people are somewhere in the first two.
1. Casual user
You want normal privacy hygiene: less ad tracking, confidence your VPN is actually working, and no obviously careless exposure. Your realistic risks are advertisers, data brokers, and basic account security — not a determined attacker targeting you personally.
What matters most: confirming your VPN doesn't leak your real IP, understanding what your public IP and DNS reveal, and using unique passwords.
Start here: What Is My IP, VPN Leak Test, Password Generator.
2. Privacy-conscious user
You actively try to limit tracking and fingerprinting, care about which companies can profile you, and want your VPN and browser settings verified rather than assumed. Your realistic risks are cross-site tracking, advertising fingerprint profiles, and data-broker aggregation — not targeted surveillance.
What matters most: checking DNS/WebRTC/IPv6 leaks specifically (not just "is my IP hidden"), understanding your browser fingerprint surface, and reviewing what a website can see about a visit.
Start here: Public Exposure Report, Browser Fingerprint Test, DNS Leak Test, WebRTC Leak Test.
3. High-risk user
You have a specific, credible reason to worry about a capable, motivated adversary — a government, an abuser with resources, or an employer/state actor who could act on what they learn. If this is you, browser-based leak tests are a useful signal but are not sufficient on their own.
What matters most: MyIPScan's tools only see what this browser session exposes — they cannot verify your operating system, your other apps, your physical security, or your full network path. At this risk level, browser tests should supplement — not replace — dedicated operational-security practices (compartmentalized devices, Tor where appropriate, and guidance from an organization built specifically for high-risk users).
Where to go beyond this site: organizations like the Electronic Frontier Foundation's Surveillance Self-Defense guide and Privacy Guides' threat-modeling resources are written specifically for this tier and go deeper than a browser-testing site can responsibly cover.
How to figure out your own level
Ask yourself these plainly, in order:
- Would anyone specifically targeting me benefit from succeeding? If the honest answer is "not really, I just don't want to be tracked by ad networks," you're a casual or privacy-conscious user, not high-risk.
- Am I worried about a company profiling me, or a person/organization acting against me? Profiling worries point to privacy-conscious; a specific person or organization points toward high-risk.
- What's the realistic worst case if my current setup fails? "More targeted ads" is a very different worst case than "physical danger" or "loss of employment/asylum status." Match your effort to the actual stakes, not to how technical a solution sounds.
A common mistake in both directions
Over-protecting wastes time and can backfire: a casual user who adopts a high-risk setup (extreme browser lockdown, constant VPN-chain switching) often ends up more frustrated and no more protected, because the actual threats they face don't require it. Under-protecting is the opposite mistake: assuming "I have nothing to hide" without checking whether a VPN is actually working, or whether a browser is leaking more than expected. Both mistakes come from skipping the threat-model question and jumping straight to tools.
What this guide does not cover
This is a framework for thinking, not a personalized risk assessment — nobody's situation fits a 3-tier list perfectly. It also does not replace professional guidance for anyone in physical danger; if that's your situation, prioritize resources built for exactly that (a domestic-violence or press-freedom organization's digital security team) over any general-purpose website, including this one.
Frequently asked questions
Do I need a VPN if I'm just a casual user?
A VPN can help with basic privacy (hiding your IP from the sites you visit, using untrusted Wi-Fi more safely) even at the casual level, but it is not mandatory. If you use one, confirm it's actually working with a VPN Leak Test rather than assuming it is.
Can browser-based tests like the ones on this site protect a high-risk user?
They can help spot browser-level exposure (IP, DNS, WebRTC, fingerprint signals), but they cannot verify your operating system, other applications, or physical security. High-risk users should treat these tests as one input among many, not a complete solution.
What's the difference between privacy and security threat modeling?
Privacy threat modeling focuses on who can observe or profile your data and activity. Security threat modeling focuses on who could actively compromise your accounts, devices, or systems. The two overlap heavily in practice — a DNS or WebRTC leak is a privacy issue that can also become a security issue if it exposes your real location or network to someone hostile.
How often should I reassess my threat model?
Reassess whenever your circumstances change significantly — a new job, a new relationship situation, travel to a different country, or a new online activity that raises your visibility. Otherwise, an annual check-in is reasonable for most people.
Is it bad to over-protect "just in case"?
Not inherently, but it has real costs — time, convenience, and sometimes drawing more attention rather than less (an unusually locked-down setup can itself look distinctive). Match your effort to your actual, honestly-assessed risk rather than the most extreme option available.
