Remote working has changed the game in cybersecurity
Just a few years ago, IT security was based on a simple premise: the company was a fortress. Back then, a firewall effectively protected the internal network, the server room housed the servers, and employees used only managed infrastructure. As a result, attackers had to breach a single, clearly defined perimeter.

Unfortunately, working remotely has completely ruined this routine.
Today, the same employee logs into the CRM system from home in the morning, uses the hotel’s Wi-Fi in the afternoon, and uses a personal tablet in the evening. It’s important to understand that each of these connections serves as an entry point for a hacker, since the company’s firewall no longer protects these dispersed devices.
The consequences of this shift are severe. According to IBM’s 2023 Cost of a Data Breach report, data breaches in remote work environments result in costs that are, on average, $173,000 higher than those of incidents in office settings. Furthermore, since 2020, the number of phishing attacks targeting remote workers has increased by more than 600%.
As a result, companies must build an IT security model designed for a distributed structure, rather than retroactively adapting legacy solutions. Today, hybrid work is the norm, and it requires a modern approach.
Why does remote work increase the risk of cyberattacks?
Before we get into specific threats, it’s important to understand that a distributed environment is structurally more difficult to secure than a traditional office. This is primarily because the boundaries of the corporate network no longer exist, and every home router has become a potential entry point for a hacker.
In an office environment, the IT department:
- monitors devices connected to the network,
- monitors network traffic and can detect anomalies,
- manages updates and configuration centrally,
- can physically respond to a suspicious incident.
Unfortunately, in a remote environment, each of these factors presents new challenges. The dispersion of devices and the lack of control over home networks drastically limit visibility into user activity. Worse still, attackers are well aware of these vulnerabilities and actively exploit every security gap.
Największe ryzyka bezpieczeństwa IT w pracy zdalnej
Unsecured home and public Wi-Fi networks
A home router is one of the most overlooked aspects of IT security. Most employees never update it, use the manufacturer’s default passwords, and don’t enable WPA3 encryption. It’s important to keep this in mind because all traffic between an employee’s device and company systems passes through the router. As a result, taking control of this single point can give a hacker access to everything your team sends.
Unfortunately, public Wi-Fi networks in cafes and hotels pose an even greater risk. Open connections are a classic vector for man-in-the-middle attacks, in which a criminal intercepts the victim’s unencrypted network traffic. As a result, the employee doesn’t notice any signs of a breach, even though the attacker already has their credentials.
Personal devices for work – the risks of BYOD
Currently, the BYOD (Bring Your Own Device) model – which means using private devices for business purposes – has become a standard in remote work. While from an employee's perspective such a solution means convenience, from an IT security standpoint, it generates serious risks.
A personal laptop may contain:
- outdated software with unpatched vulnerabilities,
- apps downloaded from untrusted sources,
- Malware installed by other people using the device,
- No disk encryption or password policy.
The company has no insight into the configuration of such a device nor the ability to enforce security standards—unless it implements the appropriate management tools.
Phishing and social engineering
It is worth noting that a remote worker is much more vulnerable to phishing attacks than a colleague in the office. This is primarily because they lack the ability to quickly verify a suspicious message. As a result, they cannot simply turn to a colleague at the next desk and ask, “Did you also receive this email from IT?” This communication barrier presents cybercriminals with a perfect opportunity.
Attackers are impersonating:
- the IT department with a request to change your password immediately,
- video conferencing platforms (Teams, Zoom) with fake invitations,
- cloud providers (AWS, Microsoft 365) with alerts about suspicious activity,
- supervisors with urgent requests for data transfers or access to data.
According to the Verizon Data Breach Investigations Report 2023, more than 74% of all data breaches involve a human element—phishing, user error, or social engineering.
Technology can mitigate the effects of phishing, but it won’t eliminate it without properly trained employees.
Poor identity and access management
The most common mistakes in identity management in remote organizations: In an office environment, access to systems was partially protected by physical security—an attacker had to gain entry to the building. In a remote setting, the only barrier is often a username and password.
The most common identity management mistakes in remote organizations:
- no multi-factor authentication (MFA),
- using the same passwords for multiple systems,
- no password rotation or password complexity policy,
- accounts of former employees that remain active after they leave the company,
- excessive user privileges – access to resources they don't need.
Hacking a single account without MFA can give an attacker access to the company’s entire infrastructure—especially if that account belongs to an administrator.
Shadow IT – unauthorized applications and services
Remote workers naturally turn to tools that make their jobs easier—even if they aren’t approved by IT. A personal Dropbox account for file sharing, WhatsApp for communicating with clients, and Trello for managing team tasks.
Shadow IT is a silent threat to security. On the one hand, every unauthorized tool poses a risk of data leakage; on the other, it leads to a complete loss of control over how information is processed. That is precisely why, given the difficulty of detecting this practice without advanced monitoring, it is considered one of the most dangerous challenges facing modern IT.
Lack of visibility and monitoring of distributed environments
This is perhaps the biggest IT security challenge when working remotely. Without the right tools, the IT department is effectively blind to what is happening on employees’ endpoints.
Ransomware attacks that ultimately cripple an entire organization often begin weeks or months earlier—with a single compromised account or infected device. Without continuous monitoring for anomalies in user behavior and network traffic, such threats go unnoticed until it’s too late.
According to IBM, the average time between an attacker’s initial access and the detection of an incident is 197 days. In environments without a SOC, this timeframe is even longer.
Best IT security practices for remote teams
Implementation of a VPN and traffic encryption
A VPN (Virtual Private Network) is the bare minimum—an encrypted tunnel between an employee’s device and the company’s infrastructure that protects data transmitted over untrusted networks. Every remote employee should use a VPN whenever connecting to company resources.
It’s important to remember that a VPN protects your network traffic—but it doesn’t replace other layers of security. A VPN alone won’t protect your business from phishing, weak passwords, or infected devices.
MFA required on all systems
Multi-factor authentication (MFA) is one of the most effective and cost-efficient methods for protecting user accounts. Even if an employee’s password is stolen through phishing or a data breach, an attacker cannot log in without the second authentication factor.
MFA should be mandatory for:
- access to company email,
- VPN systems,
- business applications (ERP, CRM),
- control panels and the cloud,
- remote access tools (RDP, SSH).
- BYOD Policy and MDM Implementation
Companies that allow the use of personal devices should implement Mobile Device Management (MDM)—a system for centrally managing end devices. MDM allows you to:
- force software and operating system updates,
- enforce password policies and disk encryption,
- remotely wipe the device in the event of theft or an employee's departure,
- separate work data from personal data on the same device.
An alternative is to implement a policy prohibiting BYOD and to provide employees with company-issued devices that have the appropriate security settings.
Regular training sessions and phishing simulations
It is worth understanding that technology is no substitute for employee awareness. Therefore, every organization should implement mandatory cybersecurity training for all departments. Particularly effective are simulated phishing attacks, as they test the team's alertness in conditions close to a real threat.
A good training program should include:
- recognizing phishing and spear phishing,
- guidelines for the safe use of public Wi-Fi networks,
- procedures for reporting suspicious incidents,
- the basics of password security and access management.
- The principle of least privilege and access segmentation
Each employee should have access only to the resources necessary to perform their job—and nothing more. The principle of least privilege minimizes damage in the event of an account compromise: an attacker who gains access to a marketing department employee’s account should not have access to financial databases or production systems.
Equally important is network segmentation—dividing the infrastructure into separate zones so that a breach in one segment does not automatically grant access to the entire network.
The Zero Trust Model – Trust No One, Verify Everyone
It is worth noting that this is a security model based on the assumption that no user, device, or application is automatically trusted—even if they are logging in from the company’s internal network. In practice, this means that every access attempt must be verified, which drastically reduces the risk of unauthorized data breaches.
In practice, Zero Trust means:
- continuous verification of the user's identity with every login,
- checking the device's security status before granting access,
- micro-segmentation – limiting lateral traffic within the network,
- logging and analyzing every access request.
Zero Trust is particularly important in distributed environments, where the traditional network perimeter no longer exists.
Continuous security monitoring – SOC for remote environments
Of course, procedures are only half the battle, as they reduce risk but never fully eliminate it. It is therefore important to accept that incidents simply happen. Consequently, what matters most is how quickly the team can detect and neutralize an intruder.
Unfortunately, small IT departments typically lack the resources to monitor hundreds of devices around the clock on their own. That is why modern companies are turning to SOC-as-a-Service, which provides continuous monitoring and minimizes response times.
Importantly, Knoxter's SOC instantly identifies:
- unusual logins and attempts to escalate privileges,
- anomalies suggesting malware,
- data leaks caused by shadow IT.
It is important to note that, thanks to real-time detection, the team reduces response times from months to minutes. This allows the company to neutralize threats instantly, thereby safeguarding business continuity and minimizing losses.
IT Security Checklist for Remote Work
A self-audit is the first step toward improving security. It’s therefore worth checking whether your organization has implemented at least basic security measures. Below is a checklist that will help identify any potential vulnerabilities in your infrastructure:
- All employees use a VPN when accessing company resources
- MFA is enabled for email, VPN, and key business applications
- Employee devices are managed centrally (via MDM or company-owned devices)
- Employees have received training on how to recognize phishing in the past 12 months
- Former employees' accounts are deactivated on the date of their departure
- The principle of least privilege is applied
- The IT environment is The network is segmented—not all use
- The IT environment is monitored for anomalies in real time
- There is a documented procedure for responding to security incidents
- Backups are regularly tested and stored in an isolated environment
It is important to note that if any of the above points remain unchecked, your organization has a real security vulnerability. In that case, it should be addressed immediately to minimize the risk of a costly incident.
Summary: IT security must keep pace with the work model
There is no doubt that the hybrid model has become a permanent fixture in the corporate landscape. For this reason, organizations operating in a distributed environment that fail to update their security strategies are taking a huge risk. Moreover, modern security is not just a collection of individual solutions, but a cohesive ecosystem. It consists of technologies and procedures, but above all, it relies on continuous monitoring that identifies anomalies in real time.
