How To Manage Your Digital Footprint

Posted on 1 October 202521 October 2025 by Vivienne Fouche

Protect your personal data – how much key information are you really exposing?

Wherever there are people, there are those who decide to prey on them – this is true for the digital world just as much as the physical. And so, before you take the fun-looking quiz that popped up in your social media feed, think twice – and learn how to manage your digital footprint!

Do you really need to know what your ‘spooky Halloween’, ‘Harry Potter alter ego’ or ‘professional wrestler’ names are, based on a combination of – let’s say – your birth month, the first letter of your name, your street address details and the name of your pets / children?

It’s clear how easy it is to start building up personal information about you based on some of those details.

Most of us have had these seemingly innocent quizzes popping up on our social media feeds at some point. But the software program that’s going to send back the amusing ‘answer’ based on the personal information you shared… might just be a hacker.

Individual pieces of data may seem harmless, but when collected, they can tell a detailed story about your habits, preferences and even personal details like your birthday or location, which allows cybercriminals to go deeper into your online profile for their own personal gain.

Let’s look at ‘digital footprints’ and how much personal information you are actually exposing to the underworld.

Footprints Across the World Wide Web

Manage your digital footprint — Learn how to manage your digital footprint!

A digital footprint means the trail of data you leave when using the Internet, and it can be used to track a person’s online activities and devices. Internet users create their digital footprint either actively or passively, through everyday activities that create it such as social media, browsing, shopping, apps and location services.

The types of data being exposed includes personally identifiable information (PII) such as a phone number or ID number, your financial data, browsing and shopping habits, location tracking, and metadata, including information about your device, your IP address and cookies. Your digital footprint can be used legitimately enough for targeted advertising, when companies use your data to categorise you and show you personalised ads; as well as for data analysis, when companies use technology to collect and analyse this data to build profiles about you – let’s say to offer you better service as a customer.

More sinisterly, though, a comprehensive footprint makes you an attractive target for hackers and scammers and puts you at risk of identity theft and scams. And everyone should be aware that your reputation and potential employment can also be affected, because your online activity can be seen by potential employers.

We look at how to reduce your online footprint.

Active Versus Passive

Active digital footprints take place when the Internet user has deliberately shared information about themselves. They include:

- Social media posts, comments and messages;

- Emails and newsletters you send and receive;

- Online purchases and shopping history; and

- Website content you upload or download.

Passive digital footprints are created when information is collected about the user without them being aware that this is happening. They include:

- Internet browsing and search history;
- Location data from your phone or devices;
- Data collected by cookies on websites; and
- Information from apps and wearable devices.

Online Privacy Tips to Protect Your Personal Data and Reduce Your Online Footprint

Here are some tips for protecting your personal data and help you to manage your digital footprint.

Double-check your privacy settings on social media to control who sees your posts.
Use search engines to check your digital footprint: You could contact the site administrator to see if information about you that you find can be removed. You could also set up Google alerts to keep an eye on your name.
Avoid oversharing on social media: Think twice before revealing your location or travel plans, or other personal information like your phone number or email address.
Avoid unsafe websites: Make sure you’re transacting with a secure website – the URL should start with https:// rather than http:// – the ‘s’ stands for ‘secure’ and indicates that the site has a security certificate. There should also be a padlock icon to the left of the address bar.
Don’t send personal information on public Wi-Fi: A public Wi-Fi network is less secure than your personal one.
Delete old accounts: This reduces your exposure to potential data breaches.
Create strong passwords and use a password manager: Using a password manager will help generate, store and manage all your passwords in one secure online account.
Don’t log in with Facebook: Every time you sign into a third-party website using your Facebook credentials, you give that company permission to mine your Facebook user data.
Keep software up to date: Cybercriminals can access a victim’s devices and data by exploiting vulnerabilities in software. You can help prevent this by keeping your software up to date.
Review your mobile use: Set a passcode for your mobile device, and when installing an app, read the user agreement. Is the app possibly going to mine personal data like your email, location and online activities?
Act fast after a breach: If a financial loss is involved, contact your bank or credit card provider. Change passwords that might have been exposed.
Use a VPN: Using a virtual private network, or VPN, can help safeguard your digital footprint. This is because VPNs mask your IP address which makes your online actions virtually untraceable.

Digital footprints matter because cybercriminals can exploit your digital footprint, for example using it for phishing for account access, or creating false identities based on your data. You can’t erase your digital footprint entirely, but you can control its visibility.

Why not use the steps outlined here to look at your online presence today and see how you can make your digital footprint more manageable, to better protect your online privacy and yourself?

Keeping your digital privacy in South Africa (and around the globe) safer and more secure will help to keep your banking and other details private and therefore safer, in turn bringing you increased peace of mind.

The message is clear: no more funny quizzes to find out your Harry Potter alter ego, because there’s nothing at all magical about being hacked.

Vox has teamed up with Norton to help individuals and also families to stay safe online – you can block hackers from accessing your devices, keep your online activity private and better protect your identity.

Frequently Asked Questions

What is a digital footprint?
A digital footprint is the trail of information you leave online from actions like social posts, searches, purchases and app use. It includes active data you deliberately share and passive data collected about your device, location and browsing habits.

Why does my digital footprint matter?
Your digital footprint can be used for personalised services and ads, but it also makes you a target for scams, identity theft and reputation risks — for example, employers or fraudsters may view or use that information.

How can I check what’s in my digital footprint?
Start by Googling your name, checking social profiles, and using Google Alerts for your name. Review privacy settings on social sites and request removal from sites or directories that publish your personal details.

What simple steps help manage your digital footprint?
Limit what you share on social media, tighten privacy settings, delete old accounts, use strong unique passwords with a password manager, and avoid logging into third‑party sites with Facebook or Google where possible.

Are online quizzes and personality apps safe?
Many quizzes ask for pieces of personal data that, when combined, can be exploited. Treat them sceptically — don’t give out real birthdates, ID numbers, addresses or your mother’s maiden name for a bit of fun.

How can I protect personal data on my mobile device and apps?
Set a passcode or biometric lock, check app permissions before installing (location, contacts, microphone), update apps and the OS regularly, and avoid using public Wi‑Fi for sensitive transactions unless you use a trusted VPN.

What should I do if my personal data is exposed in a breach?
Act quickly: change passwords, notify your bank or card provider if financial details were involved, enable two‑factor authentication, and monitor accounts for unauthorised activity or identity fraud.

Will a VPN and password manager improve my digital privacy?
Yes. A reputable VPN masks your IP and helps protect activity on public networks, while a password manager generates and stores strong unique passwords — together they significantly reduce your exposure when managing your digital footprint.

Costs of a Data Breach to Your South African Business

Posted on 1 October 202521 October 2025 by Vivienne Fouche

Money, reputation, customers: A cyberattack is costly in multiple ways

It’s estimated that cyberattacks will cost the South African economy R2.2 billion in 2025. That’s according to a recent Vodacom Business report, which revealed that 80% percent of South African businesses had experienced a cyberattack during 2024.

These are incredibly high numbers.

Firstly, the fact that 8 out of every 10 local businesses was attacked last year underscores the persistence and determination of cybercriminals as they attempt data breaches.

As for the resultant costs of a data breach – R2.2 billion – these add up in a number of different ways, both directly and indirectly.

Firstly, there’s the ransomware that must be paid if the cybercriminals succeed in breaching an organisation and encrypting its data. The attackers then demand a ransom to provide the decryption key and restore access, sometimes threatening to leak stolen data if the payment isn’t made.

Even if the organisation pays the ransom, this is not always a guarantee that the decryption key will be handed over. It seems that there isn’t always ‘honour among thieves’.

In addition, there will be incident response and recovery costs to pay, with significant expenses for hiring in consultants to carry out recovery efforts, forensic investigations and system restoration.

But these direct costs aren’t the end of the story – indirect costs are also incurred as a result of a successful cyberattack.

This includes through operational downtime, leading to lost productivity and revenue; reputational damage, causing potential new customers choosing to go elsewhere; and legal and regulatory costs, with companies facing possible fines from regulatory agencies for failing to protect sensitive data (and there may even be lawsuits from affected parties).

Costs of a Data Breach in South Africa

Over the past two years, advancements in artificial intelligence and machine learning have equipped cybercriminals to orchestrate and successfully execute sophisticated cyberattacks. From phishing, malware, ransomware, identity theft, hacking, social media fraud to social engineering, cyber threats are no longer simply a technology problem but a business problem.

South Africa is no exception – we were recently ranked as being the number 1 target for cyberattacks in Africa. No matter its size, every business is a possible target for cyberattackers[1].

Other frightening statistics include the following:

40% of ransomware attacks in Africa recently occurred in SA; and
We also claimed 35% of infostealer incidents across the continent.

Factors contributing to SA’s #1 position as most attacked country in Africa include:

A lack of cybercrime investment;
Ineffective law enforcement prosecution; and
Lack of awareness.

Cybersecurity incidents on government bodies, such as the South African Weather Service and the National Health Laboratory Service, and well-established brands like Dis-Chem, show how vulnerable local organisations can be in the face of these rising threat levels.

How to Reduce the Expected Cost of a Data Breach

Organisations that proactively reduce their attack surface and improve recovery capability materially lower the potential cost of a breach. Focus on four priority areas:

Prevent

Deploy layered defences (endpoint protection, firewall, email security and web filtering).
Train staff regularly on phishing, social engineering and secure practices.
Apply strong access controls and multi-factor authentication.

Detect

Implement continuous monitoring and logging to identify anomalous behaviour quickly.
Use managed threat detection services where in-house capability is limited.

Respond

Maintain a tested incident response plan with defined roles, communication templates and escalation paths.
Engage forensic and legal partners on retainer to reduce response time.

Recover

Ensure immutable, tested backups and documented recovery runbooks.
Use segmented network design and least-privilege policies to limit lateral movement.

Protecting Your Organisation from Cyberattacks

A firewall is your network’s first line of defence against the cybersecurity threats of the public internet. You could think of firewalls as the gatekeepers to the public internet for your network users, filtering out threats and enabling them to connect safely to the sites and applications where they need access to do their work.

Existing as both hardware and software, firewalls are designed to restrict access to your organisation’s sensitive data while helping you monitor your network for suspicious activity.

Too many organisations still see cyberattacks as an irrelevant global problem, not a high-risk local threat. It’s imperative to make sure that your company has the necessary defence mechanisms in place, starting with identifying the risks and implementing an incident response plan.

Frequently Asked Questions

What is the typical data breach cost for South African businesses?
Data breach cost varies widely, but South African firms face direct and indirect losses including ransom payments, recovery, legal fees and reputational damage, often totalling tens of thousands to millions of rand.

How does ransomware affect data breach cost?
Ransomware dramatically increases data breach cost through demanded payments, extended downtime, forensic investigations and possible double extortion, as well as the risk that paid ransoms do not yield reliable decryption.

Are small businesses in South Africa at risk of cyberattacks?
Yes, small businesses are frequent targets. This is because limited budgets, weak defences and lack of awareness make them vulnerable, increasing the likelihood of high data breach cost and reputational harm.

What are the most common cyber threats facing South African businesses?
Phishing, malware, ransomware, identity theft and social engineering are most common, driven by AI‑enhanced tactics and posing major challenges for cybersecurity South Africa across sectors.

How much does operational downtime add to the overall data breach cost?
Operational downtime can multiply losses through lost revenue, reduced productivity and contractual penalties, often matching or exceeding direct remediation costs in severe incidents.

Is paying a ransom a reliable way to restore data?
No. Paying a ransom is risky, because attackers may not provide decryption or may demand more, and paying can increase overall data breach cost and legal or ethical complications.

What indirect costs should businesses anticipate after a cyberattack?
Anticipate indirect costs like reputational damage, customer churn, regulatory fines, legal claims, increased insurance premiums and long‑term loss of market trust, all contributing substantially to data breach cost.

What practical steps reduce data breach cost and improve cybersecurity in South Africa?
Implement firewalls, regular backups, employee training, incident response plans and patch management; invest in monitoring and third‑party partnerships to lower data breach cost and strengthen cybersecurity South Africa defences.
