IT security when working from home: protecting company data, access and devices

Many companies set up home working arrangements quickly but never secured them consistently. A familiar pattern emerges in practice: employees can access company data, but security standards have only been partially implemented. They use home Wi-Fi, store files locally, work with tools whose approval status is unclear or report security incidents too late. This increases the risk of phishing, data leakage and ransomware, and makes incidents harder to trace.

Common security risks when working from home

Remote work moves business processes into environments over which the company has limited control. This is where the greatest weaknesses often lie. Home routers are frequently inadequately secured, devices are used for both personal and business purposes, and security updates are not always installed reliably. Employees working outside the office also make decisions on the spot, for example about using new tools or sharing files.

The risks become particularly serious when sensitive information is processed without clearly defined safeguards. A single compromised laptop, lost mobile device or successful phishing attack can expose internal accounts, customer data or confidential documents. Securing work from home therefore means treating remote workplaces as realistic targets for attack and protecting them accordingly.

Secure access is the foundation of IT security when working from home

Protecting every point of access to company systems is central to securing remote workplaces. Employees working from home must not rely on a username and password alone to access email, cloud services, internal portals or VPN services. Multi-factor authentication should be standard, rather than an optional extra.

The quality of login credentials is equally important. Weak or reused passwords are among the most common entry points for attackers. Companies should therefore establish mandatory password policies and use password managers where possible. They should also check which accounts actually need remote access. Not every service needs to be accessible from outside the company, and not every role needs the same level of access.

Here, IT security for working from home is primarily about managing access deliberately. Regularly reviewing permissions and limiting them to what is necessary significantly reduces risk.

Secure endpoint devices consistently

The security of a home working setup depends on the devices used. Company laptops, tablets and smartphones should be centrally managed, kept up to date and protected in line with clear minimum standards. These include automatic locking, device encryption, up-to-date operating systems, security software and the ability to lock or wipe devices remotely.

Problems often arise when the boundaries between personal and business use become blurred. Clear rules are needed when employees use their own devices. Without defined standards, a company can quickly find itself dependent on business data while having no control over device security, update status or installed applications.

For this reason, securing work from home involves more than technical safeguards. Companies also need to establish which devices are permitted and the conditions under which they may be used.

Do not overlook home networks and connections

Many security plans focus on company systems while paying little attention to employees' home networks. Yet this environment often determines how secure remote work actually is. Outdated routers, weak Wi-Fi passwords and networks shared with many personal devices increase risk unnecessarily.

Companies should therefore define simple, understandable minimum requirements. These include strong Wi-Fi passwords, up-to-date router firmware and careful use of unfamiliar or public networks. Encrypted connections are essential when accessing company resources, for example through a VPN or modern identity-based access controls.

Companies must not assume that every employee can assess technical details independently. Clear requirements that are easy to follow are more useful than rules that first need to be interpreted during an emergency.

Manage tools, data and shadow IT when working from home

Shadow IT is an often underestimated problem in remote work. Employees look for practical ways to share files quickly, hold meetings or collaborate on content. Without clear approval rules, they may turn to messaging apps of their own choosing, personal cloud storage or collaboration tools adopted on the spot. This can create security gaps, data protection problems and a loss of control.

Companies should therefore clearly define which tools may be used for remote work and which may not. It is just as important to establish where data is stored, how it is shared and who may access it. Without these rules, even effective individual safeguards have limited value.

In practice, IT security for working from home often improves when companies establish a few sensible standards instead of imposing as many bans as possible. Employees need approved tools that work. Only then will they accept security requirements.

Phishing remains a leading day-to-day concern

Phishing remains one of the biggest real-world threats when working from home. Fake login pages, convincing fraudulent emails, tampered sharing links and supposedly urgent requests to employees often work particularly well remotely because it is harder to check directly with colleagues in the office.

Providing technology alone is therefore not enough. Employees need to know which warning signs to look for: suspicious senders, unusual payment requests, unexpected requests for passwords or unexpected file shares. They also need straightforward reporting channels. Anyone who suspects an incident should immediately know whom to contact.

This shows why IT security for working from home must also be practical to implement. Clear, regular awareness reminders work better than infrequent mandatory training that has little connection to everyday work.

Define clear procedures for incidents and outages

A security incident is often noticed sooner in the office. At home, things are different. When a device has been compromised, an account is locked or data has been shared accidentally, valuable time can be lost. Employees may be unsure whether an incident has actually occurred, what immediate action to take and whom to inform.

Companies should therefore define clear procedures. What should employees do if a device is lost? How should they report suspected phishing? Which systems must be locked down immediately? Who decides what happens next? These procedures ease the pressure in an emergency and make security management dependable outside a conventional office setting.

Why companies need a practical approach

Not every company needs a complex remote work security programme from the outset. What is almost always missing, however, is a realistic assessment of the actual risks. A practical approach starts here: which devices are in use, what access is available, which tools are being used, where is sensitive data stored and which vulnerabilities matter most?

Rather than merely documenting security measures as a formality, companies should set priorities and address the areas with the greatest impact first. These are often straightforward issues: robust access controls, up-to-date devices, clear rules for tools, security awareness and effective incident procedures.

IT security for working from home is effective when it goes beyond paperwork, improves everyday work and demonstrably reduces risks.

Take a structured approach to securing remote workplaces

Companies whose employees work from home regularly or permanently should assess their remote workplaces systematically. What minimum standards apply? Where are the blind spots? Which measures can be implemented quickly, and which issues require a strategic decision?

This is where Verisite can help: with a clear view of real risks, practical measures and solutions that work in everyday business, without unnecessary complexity. Effective IT security for working from home comes from clear decisions, well-chosen priorities and an approach that employees actively support.
