VPNs have now entered the mainstream. Many users will only adopt these services to access geolocation-blocked content -- such as websites and apps banned in select countries -- for example, a user in the United States could make themselves appear to be located in the United Kingdom, and vice versa. However, VPNs have also surged in popularity in response to increased surveillance, making their use a popular option for activists or those in countries ruled by censorship.

For a more detailed look at how VPNs operate, check out our guide. VPNs are not a silver bullet for security; far from it, but they can help mask your online presence.

It is worth noting, however, that VPN usage is banned in some countries. Premium, paid services are often more trustworthy. Free options are often slower and will offer limited bandwidth capacity. VPNs cost money to run and so providers will also require users of free services to agree to alternative means for them to turn a profit -- and this may include tracking and selling your data.

Remember, when you are using a free service, whether it's a VPN or Facebook, you are the product and not the customer. If you're technically able, you could also set up your own private VPN.

A handy set of instructions can be found here. The most important element to consider when deciding on a VPN is trust. Using a VPN requires all your traffic to go through a third-party. If this third-party VPN is unsecured or uses this information for nefarious reasons, then the whole point of using a VPN for additional privacy is negated.

Conflicts of interest, VPN providers being hosted in countries of which governments can demand their data, and sometimes less-than-transparent business practices can all make finding a trustworthy option a complex and convoluted journey.

VPN services: The ultimate guide Why free VPNs are not a risk worth taking. This kind of advice is repeated ad nauseam but it is worth saying again: The best password managers for Get rid of the sticky notes and get peace of mind. Choose a password manager to secure your digital life. However, it is difficult to remember complicated password credentials when you are using multiple online services, and this is where password vaults come in.

Password managers are specialized pieces of software used to securely record the credentials required to access your online services. Rather than needing to remember each set of credentials, these systems keep everything in one place, accessed through one master password, and they will use security measures such as AES encryption to prevent exposure.

Vaults may also generate strong and complex passwords on your behalf, as well as proactively change old and weak ones.

Online security 101: How to protect your privacy from hackers, spies, and the government

It is true that many popular password managers and vaults do have vulnerable design elements that can be exploited on already-compromised machines , but when you balance risk, it is still recommended to use such software. Two-factor authentication 2FA is a widely-implemented method of adding an extra layer of security to your accounts and services after you have submitted a password.

The most common methods are via an SMS message, a biometric marker such as a fingerprint or iris scan, a PIN number, pattern, or physical fob. Using 2FA does create an additional step to access your accounts and data. How to enable 2FA: Tutorials for other major services can be found at Turn it On. You can also use standalone mobile apps to add 2FA to websites. Two-factor authentication: Mobile devices can act as a secondary means of protection for your accounts through 2FA, but these endpoints can also be the weak link that completely breaks down your privacy and security.

Both Apple iPhones and mobile devices based on Google's Android operating system have sold by the millions. Android has maintained the lion's share of the global smartphone and tablet market for years, but due to its popularity, the majority of mobile malware samples are geared towards this OS.

The open-source nature of Android has also opened the way for hackers to search for vulnerabilities in its code, but to combat this, Google does run a bug bounty program and consistent security patch cycle. Google has previously said that Android security is now as good as iOS , but we are still waiting to see the real-world evidence of this claim. The first and easiest way to keep mobile devices on either platform secure is to accept security updates when they appear over the air.

These patches resolve new bugs and flaws, as well as sometimes provide performance fixes, and can keep your device from being exploited by attackers. It sounds simple, but many of us don't do it -- make sure your mobile device is locked in some way to prevent its physical compromise.

You can turn on your iPhone 's Passcode feature to enter a four or six-digit passcode, as well as select the 'custom' option to set either a numeric or alphanumeric code.

On Android , you can choose to set a pattern , PIN number, or password with a minimum of four digits. Face recognition, iris scanning, and fingerprints are biometric authentication options found on modern iPhones and Android devices. These services can be convenient, although it is worth noting that in the US, law enforcement may be able to force you to unlock your devices as biometrics are not protected under the Fifth Amendment.

We want to stop ourselves from being monitored without consent, but some technologies can be beneficial for tracking down our own lost or stolen property. Find my iPhone is a security feature for iOS devices that you can enable to allow you to track your device through iCloud. The system also includes a remote lock to prevent others from using your iPhone, iPad or iPod Touch in the case of theft. Scroll to the bottom to tap Find my iPhone, and slide to turn on. Google's Find My Device can be used to ring a missing device, remotely secure your smartphone, and also wipe all content on your stolen property.


The service is automatically made available by default once a Google account is connected to your device but it does require the device to be turned on, to have an active internet connection, and to have both location and the Find My Device feature enabled. Two-thirds of all Android antivirus apps are frauds The 10 best smartphones you can buy right now. USB Restricted Mode: A handy security feature introduced in iOS If there have been apps you simply had to install outside of Google Play, make sure the "Unknown Sources" or "Install Unknown Apps" option is not left open afterward.

Sideloading isn't necessarily a problem on occasion but leaving this avenue open could result in malicious. APKs making their way onto your smartphone. Depending on your smartphone's model, you may have to enable device encryption, or some will be encrypted by default once a password, PIN, or lock screen option is in place. You can also choose to enable the Secure Folder option in the same settings area to protect individual folders and files. The 10 best ways to secure your Android phone. Rooting your device to allow the installation of software that has not been verified by vendors or made available in official app stores has security ramifications.

You may not only invalidate your warranty but also open up your device to malware, malicious apps, and data theft. The malware specifically targeted jailbroken iOS devices, leading to the theft of , Apple accounts and their passwords. Change these privacy and security settings now Facebook makes GDPR push with new data privacy settings.

There was once a time when Pretty Good Privacy PGP was one of only a handful of options available to secure and encrypt your online communication that existed. PGP is a program that can be used for cryptographic protection, however, PGP is complicated to set up and use and there are other options out there that are more palatable to the average user. Vulnerabilities were found in the system last year but have since been patched.

Signal is widely regarded as the most accessible, secure messaging service in existence today. Available for Android, iOS, MacOS, and Windows, the free app -- developed by Open Whisper Systems -- implements end-to-end encryption and no data is stored by the company's servers, which means that none of your conversations can be seized or read by law enforcement or hackers. In order to use the service, you will need to tie a phone number to the app. You can also use Signal to replace traditional SMS messaging, but the same encryption and protections do not apply unless both recipients are using Signal.

WhatsApp is an alternative messaging app, which completed a rollout of end-to-end encryption across all compatible devices in Available for Android, iOS, Windows Phone, Mac, Windows, and desktop, the messaging app is a simple and secure means to conduct chats between either a single recipient or a group.

Having grown even more popular in recent years and now boasting over one billion users, WhatsApp is certainly worth downloading to replace traditional chat apps. However, to tighten things up, make sure you visit the Chat Backup option in "Chats" and turn it off. Apple's iMessage, a communications platform that comes with Mac and iOS products, is another option if you want to secure and protect your digital communications.

Messages are encrypted on your devices via a private key and cannot be accessed without a passcode. However, if you choose to back up your data to iCloud, a copy of the key protecting these conversations is also stored -- and this has the possibility of being accessed by law enforcement. In order to keep your messages truly private, turn off the backup option. Apple will then generate an on-device key to protect your messages and this is not stored by the company.

In addition, only conversations taking place between iPhones -- rather than an iPhone and Android device, for example -- are encrypted. Facebook Messenger is not encrypted by default. The chat service does, however, have a feature called " Secret Conversations " on iOS and Android -- but not the standard web domain -- which is end-to-end encrypted. In order to start a secret conversation , go to the chat bubble, tap the "write" icon, tap "Secret," and select who you want to message.

You can also choose to set a timer for messages to vanish. A word of warning, however: Not only is Facebook constantly under fire for its attitude to the privacy and security of its users and their data, but US law enforcement is reportedly attempting to pressure the social network into planting a backdoor into Facebook Messenger to monitor conversations.

With other end-to-end options available, it's not worth the risk. Telegram , which received over three million new signups during the Facebook outage in March , is another popular chat application worth noting as many presume chats made through this app are automatically secure and encrypted -- which is not the case.

These particular chats are device-specific and include a self-destruct option. It is also worth keeping an eye on the rumored, upcoming Facebook Messenger, WhatsApp, and Instagram merger. Facebook CEO Mark Zuckerberg has reportedly ordered end-to-end encryption services to be added to the combined platform to create secure, cross-app messaging, which may make the combined service a future possibility for secure chats.

However, the integration is not expected to be ready for commercial release until Why social media fatigue is spreading The hacker's paradise: Social networks. No matter which mobile operating system you have adopted, downloading apps from verified, trusted sources such as Google Play and Apple's App store is always the best option to maintain your security and privacy.

Apps can request a variety of permissions including sensor data, call logs, camera and microphone access, location, storage, and contact lists. While many legitimate apps do require access to certain features, you should always make sure you are aware of what apps can access what data to prevent unnecessary security risks or information leaks.

CCleaner , Pokemon Go, Meitu , and Uber have all come under fire for privacy-related issues in the past and the problem of data collection and extended business permissions will likely carry on in the future. To be on the safe side, any time you no longer need an application, you should also simply uninstall it. Mobile malware is far from as popular as malicious software that targets desktop machines but with these variants infecting Android, iOS, and sometimes making their way into official app repositories, they are worth a mention.

The types of malware that can hit your mobile device are varied, from Trojans and backdoors to malicious code that focuses on the theft of valuable information, such as online banking credentials. The most common way that such malware can infiltrate your smartphone is through the installation of malicious apps, which may actually be malware, spyware, or adware in disguise. It's recommended that you download and install an antivirus software solution for your mobile device, however, you will probably be safe enough as long as you do not jailbreak your phone and you only download app.

However, malicious apps do sneak into these official stores as well. Android security: Malicious apps sneak back into Google Play Are enterprise app users growing more security savvy? Many email providers now encrypt email in transit using TLS, but there are few email services, if any, which you can truly consider percent "secure" due to government laws, law enforcement powers, and the difficulty of truly implementing strong encryption in email inboxes beyond using PGP to sign messages.

However, ProtonMail is worth considering. The open-source email system is based in Switzerland and therefore protected under the country's strict data protection laws. Emails are end-to-end encrypted which prevents ProtonMail -- or law enforcement -- from reading them. In addition, no personal information is required to open an account. These are the 12 most common phishing email subject lines Phishing alert: One in 61 emails in your inbox are scams.

Now that you've begun to take control of your devices, it is time to consider what data is floating around the internet that belongs to you -- and what you can do to prevent future leaks.

The free search engine of sorts can be used to check your email accounts and linked online services for the exposure of credentials caused by data leaks. If you find you have been 'pwned,' stop using all the password combinations involved immediately -- not only in the case of the compromised account but across the board.

If you are a user of Google services, the Privacy checkup function can be used to stop Google from saving your search results, YouTube histories, device information, and for you to decide whether you are happy for the tech giant to tailor advertising based on your data.

Make sure you also take a look at your main Google Account to review security settings and privacy measures. The Security checkup page also shows which third-party apps have access to your account and you can revoke access as necessary. Social networks can be valuable communication tools but they can also be major sources of data leaks.

It is not just friends and family that might be stalking you across social media -- prospective employers or shady characters may be doing so, too, and so it is important for you to lock down your accounts to make sure only the information you want to be public, is public. To begin locking down your account, go to the top-right corner, click the downward arrow, and choose "Settings," which is where the majority of your options for privacy and account safety are based.

Under this tab, you can choose to enable 2FA protection, view the devices in which your account is actively logged on, and choose whether to receive alerts relating to unrecognized attempts to log in. Review activities: Under Activity Log , you can review all your activity across the social network, including posts published, messages posted to other timelines, likes, and event management.

You can use the "edit" button to allow something on a timeline, hide it, or delete it outright -- a handy function for wiping clean your older timeline.

Hello World!

Download data: Under this tab, you can choose to download all the data Facebook holds on you. Privacy Settings and Tools: Here, you can choose who can see your future posts. For the sake of privacy, it is best to set this to friends only, unless you are happy for such content to automatically be made public.

How people can find and contact you: You can tighten up your account by also limiting who can send you friend requests, who can see your friend lists, and whether people are able to use your provided email address or phone number to find your profile.

A particular feature you may want to turn off is the ability for search engines outside of the network to link to your Facebook profile. Turn off this to prevent Facebook from gathering a log of your location history. Face recognition: Another feature you should consider turning off -- it's unnecessary. Apps and websites: Under this tab, you can see a list of third-party services that have been logged into using your Facebook credentials and whether they are active.

Ad Preferences, advertisers: A settings option that has been heavily expanded upon since the Cambridge Analytica scandal , in this section, you can review what Facebook believes are your interests, a list of advertisers that "are running ads using a contact list that they or their partner uploaded which includes information about you," and you can manage personalized ad settings -- at least, to a point.

Your interests: If you select this tab you will see topics, such as property, finance, food, and education, which are collated based on ads or promotional material you have previously clicked on.

In order to remove a topic, hover over the option and select the "X" in the top right. The same principle applies to the "Advertisers" tab. Your information: There are two tabs here that are both relevant to your online privacy and security. The first tab, "About you," allows you to choose whether Facebook can use your relationship status, employer, job title, or education in targeted advertising. The second tab, "Your categories," includes automatically generated lists of topics that the social network believes are relevant for ad placement -- all of which can be hovered over and removed.

Ad Settings: To further thwart targeted ads, consider saying no to all the options below. Another section to mention is under the " About Me " tab in Facebook's main account menu. Here, you can choose whether to make information public whether globally or to your friends , or only available to you. This information includes your date of birth, relationship status, contact information, and where you've lived.

Under the "Settings" tab there is a variety of options and changes you should implement to improve the security of your account. Login verification: After you log in, Twitter will ask you for additional information to confirm your identity to mitigate the risk of your account from being compromised. Password reset verification: For added security, this requires you to confirm your email or phone number while resetting your password.

Privacy and safety: You can deselect location tracking and stop your locations being posted at the same time you send out a tweet, and there is also an option for removing all past location data from published tweets in your history.

In this section, you will also come across " Personalization and data ," which allows you to control -- to an extent -- how the social network personalizes content, collects data, and what information is shared with third-parties.

You have the option to choose not to view personalized adverts, but the main setting you need to be aware of is for sharing.

Described by Twitter as an option to permit the company to "share non-public data, such as content you've seen and your interests, with certain business partners for uses like ads and brand marketing," you should consider saying no.
