Company-issued laptops, smartphones, and tablets have become indispensable tools in today's workplace. They allow employees to collaborate from virtually anywhere, access cloud-based applications, communicate with customers, and remain productive whether working from headquarters, a home office, or while traveling. As businesses continue investing heavily in digital transformation and artificial intelligence, work devices have become gateways to some of an organization's most valuable information.
That convenience also comes with significant responsibility. Every employee plays an important role in protecting company data, customer information, intellectual property, and business operations. According to IBM, the global average cost of a data breach reached $4.88 million in 2024, the highest amount ever recorded. Verizon's annual Data Breach Investigations Report also continues to show that the human element contributes to the majority of cybersecurity incidents, highlighting how employee decisions often determine whether an attack succeeds or fails.
Cybersecurity is no longer just an IT issue. It has become a business issue, a customer trust issue, and increasingly, a career issue. Professionals who demonstrate sound security habits help reduce organizational risk while reinforcing their reputation as dependable employees.
Here are ten things every employee should avoid doing on a work device.
1. Installing Software Without IT Approval
Downloading a seemingly harmless browser extension, AI assistant, PDF converter, file-sharing application, or productivity tool can introduce serious security risks.
Unauthorized software creates what security professionals call shadow IT—technology that exists outside an organization's approved systems. Even legitimate applications may request excessive permissions, collect sensitive data, or introduce software vulnerabilities that bypass corporate security controls.
Cybercriminals frequently disguise malware as free utilities, browser plug-ins, video players, or software updates because they know employees often install them without consulting IT.
Rather than downloading software independently, employees should request approval through their organization's established process. Many companies maintain approved software libraries or provide secure alternatives that deliver the same functionality without introducing unnecessary risk.
2. Saving Personal Files on Company Equipment
Using a work laptop to store family photos, tax returns, medical records, travel itineraries, resumes, or personal financial documents may seem convenient, but it can create unexpected problems.
Company devices remain the property of the employer. They may be audited, serviced, remotely wiped, replaced, or reclaimed when employment ends. Personal files stored on those devices could be deleted during routine maintenance or become accessible during legitimate corporate investigations.
Keeping personal information on privately owned devices or secure personal cloud storage protects your privacy while keeping business systems focused on work-related information.
Maintaining a clear separation between personal and professional data also simplifies compliance with corporate information security policies.
3. Allowing Family or Friends to Use Your Work Device
Remote work has made company laptops more visible inside the home, but that does not make them household computers.
Allowing a spouse to check email, a child to stream videos, or a friend to browse the internet using your company device introduces unnecessary risk. Unauthorized users could accidentally delete files, install malware, change security settings, or gain access to confidential client information.
Many organizations explicitly prohibit anyone other than the assigned employee from using company-issued equipment.
Treating a work computer as business equipment—not a family device—helps protect both sensitive information and your professional accountability.
4. Logging Into Personal Accounts
Many employees occasionally check personal email, online banking, shopping sites, or social media during the workday. While that may seem harmless, mixing personal and business activities increases security and privacy risks.
Many employers reserve the right to monitor activity conducted on company-owned equipment in accordance with applicable laws and organizational policies. Employees should therefore assume that work devices are intended primarily for business use.
Using personal devices for personal accounts reduces the likelihood of accidentally exposing passwords, confidential information, or browsing history while maintaining a healthier separation between work and personal life.
5. Using Public Wi-Fi Without Proper Protection
Coffee shops, hotels, airports, conference centers, and restaurants offer convenient internet access, but not every wireless network is secure.
Cybercriminals frequently create fraudulent Wi-Fi hotspots that mimic legitimate networks in order to intercept communications or steal login credentials.
Whenever working remotely, employees should follow company security policies by using approved VPN connections, enabling multi-factor authentication, and avoiding sensitive business transactions over unsecured networks.
With hybrid work becoming standard across many industries, secure remote connectivity has become an essential professional habit rather than an optional precaution.
6. Uploading Confidential Information Into Public AI Tools
Artificial intelligence is transforming how employees write, analyze data, summarize meetings, create presentations, and solve problems. According to McKinsey, generative AI could contribute between $2.6 trillion and $4.4 trillion in annual global economic value, making it one of the most significant productivity technologies ever introduced.
However, convenience should never come at the expense of confidentiality.
Many organizations prohibit employees from entering sensitive information into public AI platforms because customer information, financial records, proprietary research, source code, legal documents, or internal strategies could potentially be retained or processed outside company-approved environments.
Instead, employees should use enterprise-approved AI platforms designed with organizational security, compliance, and privacy requirements in mind.
7. Ignoring Software Updates and Security Policies
Software updates rarely arrive at convenient times, yet postponing them leaves devices exposed to known vulnerabilities.
Operating system updates, browser patches, antivirus signatures, and application upgrades often address newly discovered security flaws that attackers actively exploit.
Organizations also require password policies, security awareness training, encryption, and multi-factor authentication because these measures dramatically reduce cyber risk.
According to Microsoft's Digital Defense Report, password attacks continue to occur at extraordinary scale every day, underscoring the importance of maintaining current security protections.
Employees who consistently follow organizational security practices help strengthen the company's overall cyber resilience.
8. Sharing Passwords or Multi-Factor Authentication Codes
Passwords remain one of the most valuable assets attackers seek to steal.
Today's cybercriminals increasingly rely on social engineering rather than sophisticated hacking techniques. They impersonate executives, coworkers, IT personnel, vendors, or financial institutions in an attempt to convince employees to reveal passwords or authentication codes.
Microsoft reports blocking thousands of password attacks every second, illustrating the enormous scale of credential theft attempts worldwide.
Employees should never share passwords, authentication codes, or security tokens with anyone. Legitimate IT personnel will never ask employees to disclose their passwords.
Using unique passwords, enterprise password managers, and multi-factor authentication significantly reduces the likelihood of account compromise.
9. Ignoring Suspicious Emails, Texts, or Messages
Phishing has evolved dramatically in recent years.
Artificial intelligence now enables attackers to create highly convincing emails, text messages, voice calls, and even video impersonations that closely resemble legitimate business communications.
Fraudulent messages commonly impersonate Microsoft 365, DocuSign, payroll departments, shipping companies, banks, executives, or HR personnel while encouraging recipients to click malicious links or surrender login credentials.
Employees should carefully verify unexpected requests, inspect sender addresses, avoid clicking suspicious attachments, and report questionable communications to their IT or cybersecurity teams immediately.
Remaining cautious for a few extra moments can prevent costly security incidents affecting the entire organization.
10. Waiting Too Long to Report a Lost or Stolen Device
Accidents happen. Laptops are left in airports. Smartphones disappear during business travel. Tablets are forgotten in taxis, restaurants, or conference rooms.
The most important action employees can take is reporting the loss immediately.
Modern IT departments can often remotely locate, lock, or erase company-issued devices before sensitive information becomes accessible to unauthorized individuals. Delaying notification only increases the amount of time attackers—or even opportunistic thieves—have to access confidential business information.
The same urgency applies when a device begins behaving abnormally. Unexpected pop-ups, unusually slow performance, unauthorized software installations, or repeated login prompts may indicate malware or unauthorized access.
Prompt reporting enables security teams to investigate quickly, minimize potential damage, and restore normal operations before a minor incident becomes a major one.
Good Security Habits Are Good Career Habits
Technology continues to reshape nearly every profession, but successful organizations understand that cybersecurity depends as much on people as it does on technology. Firewalls, encryption, artificial intelligence, and endpoint protection all play important roles, yet employees remain the first and most effective line of defense.
Developing strong digital habits does more than protect company systems. It demonstrates professionalism, builds trust with managers and clients, supports regulatory compliance, and contributes to a culture of accountability across the organization.
Simple practices—such as using approved software, separating personal and work activities, protecting passwords, reporting suspicious activity, and respecting company security policies—can prevent costly incidents while strengthening an employee's long-term professional reputation.
As organizations continue embracing hybrid work, cloud computing, and artificial intelligence, professionals who consistently practice responsible device management will be well positioned to thrive in an increasingly connected workplace.
