Learn Reduce Your Footprint

Footprint Defense

The best defense is knowing your own footprint: audit yourself like an investigator, opt out of data brokers, lock down social-media privacy, strip metadata before posting, and compartmentalize identities with per-service alias emails.

You cannot protect what you have not measured. Start by searching for yourself the way an OSINT investigator would — name, email, phone, photos, usernames — to map what is already public.

Then shrink the surface: submit opt-out requests to data brokers, lock down social-media privacy settings, and strip EXIF and document metadata before you post anything.

Finally, compartmentalize. A unique alias email per service means a single breach or scrape cannot stitch your accounts into one profile. This is practical anti-doxxing hygiene for staff and executives.

Audit yourself first — search like an investigator.

Opt out of data brokers and lock down social.

Strip metadata and use per-service alias emails.

defense:
  audit: search-yourself-first
  opt_out: data-broker-removal
  privacy: lock-down-social
  metadata: strip-before-posting
  separation: alias-emails-per-service

Read the implementation

Connect each part of the code to the concept before you type.

1. Audit yourself

The best defense starts by searching for yourself the way an investigator would, so you see what is already exposed.

audit: search-yourself-first

2. Opt out of brokers

Data brokers aggregate and resell personal records; submitting removal requests shrinks the public profile attackers buy.

opt_out: data-broker-removal

3. Lock down social

Tightening social-media privacy settings stops casual scraping of your posts, friends, and location history.

privacy: lock-down-social

4. Strip metadata

Photos and documents carry EXIF and author metadata; strip it before posting so you do not leak GPS coordinates or device IDs.

metadata: strip-before-posting

5. Compartmentalize

Using a different alias email per service prevents one breach from linking all your accounts together.

separation: alias-emails-per-service
