Top 5 Online Privacy Tips From Expert

That old adage just doesn’t ring true in an age where intelligence agencies consider anyone within three “hops” of their surveillance targets fair game for scrutiny. Consider this: The average Facebook user, with just 190 friends, has over five million people in their extended network with just those third-degree connections (friends of friends of friends).

06 Jan 2016

Online privacy is not only a personal preference. It’s a basic need for anyone who uses the internet. The idea that “you don’t need privacy unless you have something to hide” is outdated. Today, your data is valuable, and many entities—governments, corporations, hackers—are after it.

At S3Corp., we take online security seriously. As a trusted partner in web and mobile application development, we apply best practices in data protection. In this article, we share important online privacy tips backed by Edward Snowden, the former NSA contractor who exposed mass surveillance practices.

These tips are easy to follow and effective. You don’t need to be a cybersecurity expert. You just need to understand how your information is tracked and how to block that access.


Why Online Privacy Matters

Every digital move you make leaves a trace. Governments monitor online activity, often reaching beyond their initial targets. For example, U.S. intelligence agencies may review data from anyone within three connections of a suspect. On Facebook, where the average user has 190 friends, this network can easily extend to five million people.

But surveillance doesn't stop with governments. Social networks, advertisers, and even email services collect user data to profile behavior. This data fuels targeted advertising and can be exposed in data breaches.

Privacy matters because it protects your identity, habits, and decisions. It’s not about hiding; it’s about maintaining control over your personal data.


Services to Avoid: Google, Facebook, Dropbox
Suggested Alternatives: DuckDuckGo, Signal, SpiderOak

Snowden has warned against using mainstream services that rely on data collection. In an interview during The New Yorker Festival, he named Google and Facebook as “dangerous services” due to their invasive practices.

Dropbox was also criticized for lacking local encryption. Files stored there can be accessed by staff or third parties with the right permissions.

Alternative solutions:

  • Use DuckDuckGo instead of Google for private searching.
  • Choose Signal for private messaging.
  • Switch to SpiderOak for file storage. It offers local encryption, so not even the provider can read your files.

2. Encrypt Your Hard Drive

Why It Matters: Protects data if your device is lost or stolen
Tools to Use: BitLocker (Windows), FileVault 2 (Mac), LUKS (Linux), Symantec Endpoint Encryption

Password protection is not enough. If someone gets physical access to your device, they can bypass your password and view your files.

Encryption adds a layer of defense by locking the data itself. Even if someone gets access to your drive, they can’t read its contents without the encryption key.

  • Windows users can activate BitLocker on Pro or Enterprise versions.
  • Mac users have FileVault 2, built into macOS.
  • Linux users can use LUKS, available in distributions like Ubuntu.
  • For advanced protection, consider Symantec Endpoint Encryption. It also secures USB drives and removable media.

3. Block Online Trackers with Browser Add-ons

Why It Matters: Stops advertisers and websites from tracking your activity
Tools to Use: Ghostery, Privacy Badger, uBlock Origin

Websites use trackers to follow your activity across the internet. These trackers build detailed user profiles to serve targeted ads. Even if you don’t mind personalized ads, this data is stored and can be shared or leaked.

To protect your browsing:

  • Install Ghostery: It shows how many trackers are on a page and lets you block them.
  • Use Privacy Badger from the Electronic Frontier Foundation. It learns which trackers to block over time.
  • Add uBlock Origin for general ad-blocking.

These tools work on most major browsers, including Chrome, Firefox, Opera, and Safari.


4. Encrypt Your Communications

Why It Matters: Keeps messages and calls private
Tools to Use: Signal, ProtonMail, Hushmail, ChatCrypt

Your emails, chats, and calls can be monitored without encryption. Even if you’re not a target, your messages can be intercepted during transmission.

To secure communication:

  • Use Signal for voice, video, and text encryption. It works on mobile and desktop.
  • Choose ProtonMail or Hushmail for encrypted email. These services don’t store readable content.
  • For web-based chats, try ChatCrypt, which encrypts messages before they leave your browser. Only the person with the shared password can read them.

5. Browse Anonymously with Tor

Why It Matters: Hides your identity and location
Tool to Use: Tor Browser

Tor stands for “The Onion Router.” It routes your internet traffic through multiple servers (nodes), making it very difficult to trace your activity or find your location.

With Tor:

  • Websites can’t track your IP address.
  • You can access restricted content based on region.
  • You reduce the chance of surveillance.

While Tor is not foolproof, it adds a strong layer of anonymity. Use it for sensitive browsing where privacy is essential. Just remember not to log in to personal accounts while using it, as that reveals your identity.


Final Thoughts: Combine Tools for Stronger Privacy

There is no one-size-fits-all solution. Online privacy requires a combination of tools and habits.

Your online privacy toolkit should include:

  • Encrypted messaging and email
  • Private search engines
  • File storage with local encryption
  • Hard drive encryption
  • Tracker-blocking browser extensions
  • Anonymous browsing tools

You don’t need all of them at once. Start with the tools that suit your current habits and build from there.

S3Corp recommends reviewing your online habits and starting with basic changes. Choose private services, use encryption, and limit tracking. These steps protect your personal data and reduce exposure to threats. Our team continues to follow best practices in security and privacy to support safe, transparent digital experiences.
