The modern office goes beyond traditional cubicles and open-plan spaces. Since the rise of remote work during and after the COVID pandemic, employees are now working from various locations, including their homes, libraries, busy coffee shops, and even vacation spots. These places, often referred to as “third places,” offer flexibility and convenience, but they can also pose risks to company IT systems.
With remote work becoming a permanent aspect of many businesses, it’s essential to adapt security policies accordingly. For instance, a coffee shop cannot be considered as secure as a traditional office, as its open environment exposes users to different types of threats. Employees need clear guidance on how to stay safe and protect company data.
Ignoring security, especially on public Wi-Fi, can have serious consequences, as hackers often target these areas to exploit remote workers. To mitigate these risks, it is vital to equip your team with the right knowledge and tools. Additionally, enforcing a robust external network security policy will help keep company data safe.
The Dangers of Open Networks
Free internet access is a significant attraction for remote workers who frequent cafes, malls, libraries, and coworking spaces. However, these networks often lack encryption or robust security measures, and even when they do have some level of protection, they do not include the specific controls found in secure corporate networks. This vulnerability makes it easy for cybercriminals to intercept network traffic and steal passwords or sensitive emails within seconds.
Attackers frequently set up fake networks that appear legitimate, using names like “Free Wi-Fi” or resembling those of nearby shops or cafes to deceive users. Once a user connects to one of these malicious networks, the hacker controlling it can see everything the user sends. This scenario is known as a “man-in-the-middle” attack.
It is crucial to remind employees never to rely on open connections. Even networks that require a password can be widely shared, posing significant risks to business data. Always exercise caution when accessing public networks.
Mandating Virtual Private Networks
The most effective tool for remote security is a VPN (Virtual Private Network). A VPN encrypts all data leaving a laptop, creating a secure tunnel through unsecured public internet connections. This encryption makes the data unreadable to anyone trying to intercept it.
Providing a VPN is essential for remote work, and employees should be required to use it whenever they are outside the office. It’s important to ensure that the VPN software is easy to launch and operate, as overly complex tools may be ignored. Whenever possible, configure the VPN to connect automatically on employee devices. This approach minimizes human error and ensures continuous protection.
Additionally, enforce mandatory VPN usage by implementing technical controls that prevent employees from bypassing the connection when accessing company servers.
The Risk of Visual Hacking
Digital threats aren’t the only risks in public spaces; someone sitting nearby can easily glance at your screen. This practice, known as visual hacking, involves stealing information simply by looking over someone’s shoulder. While it may seem low-tech, it is highly effective and difficult to track. Employees often forget how visible their screens are to those passing by, putting sensitive client data, financial spreadsheets, and product designs at risk of being seen and potentially photographed by malicious individuals.
To address this vulnerability, it’s important to issue privacy screens to all employees who work remotely. Privacy screens are filters that make laptop and monitor displays appear black from the side, allowing only the person directly in front of the screen to see the content. Some devices even come with built-in hardware privacy screens that further obscure content from anyone viewing it at an angle.
Physical Security of Devices
Leaving a laptop unattended is a recipe for theft. In a secure office, you might walk away to get water or even leave the office and expect to find your device in the same place, untouched. In a coffee shop, that same action can cost you a device, since thieves are always scanning for distracted victims and are quick to act.
Your remote work policy should stress the importance of physical device security. Employees must keep their laptops with them at all times and never entrust them to strangers. A laptop can be stolen and its data accessed in just seconds. Encourage employees to use cable locks, particularly if they plan to remain in one location for an extended period. While not foolproof, locks serve as a deterrent, especially in coworking spaces where some level of security is expected. The goal is to make theft more difficult, and staying aware of the surroundings helps employees assess potential risks.
Handling Phone Calls and Conversations
Coffee shops can be noisy, but conversations still travel through the air. Discussing confidential business matters in public is risky, as you never know who might be listening. Competitors or malicious actors could easily overhear sensitive information. Employees should avoid discussing sensitive matters in these “third places.” If a call is necessary, they should step outside or move to a private space, such as a car. While headphones prevent others from hearing the other side, the employee’s own voice can still be overheard.
Creating a Clear Remote Work Policy
Employees shouldn’t have to guess the rules. A written policy clarifies expectations, sets standards, and supports training and enforcement. Include dedicated sections on public Wi-Fi and physical security, and explain the reasoning behind each rule so employees understand their importance. Make sure the policy is easily accessible on the company intranet. Most importantly, review this policy annually as technology changes. As new threats emerge, your guidelines must also evolve to counter them. Make routine updates to the policy, and reissue the revised versions to keep the conversation about security alive and ongoing.
Empower Your Remote Teams
While working from a “third place” offers flexibility and a morale boost, it also requires a higher level of vigilance. This makes prioritizing public Wi-Fi security and physical awareness non-negotiable, and you must equip your team to work safely from anywhere. With the right tools and policies, you can manage the risks while enjoying the benefits of remote work. Success comes from balancing freedom with responsibility, and well-informed employees serve as your strongest line of defense. Protect your data, no matter where your team works.
