Why should every company
implement Zero Trust?
Zero Trust model is key to surviving cyber threats
In 2025, one thing has become abundantly clear: traditional information security requires a new approach alongside it. Remote work, cloud-based systems, generative AI, and increasingly sophisticated identity attacks have rendered old approaches inadequate. Cyber criminals no longer break in – they log in.
Modern technology allows cyber criminals to constantly find new and more creative ways to carry out attacks, and for this reason many companies have moved to implement "Zero Trust" -model, the idea of which is that nothing is trusted. Zero Trust -model assumes that the network environment is under constant attack and all data traffic, both outgoing and incoming, is under surveillance. Many companies have made expensive purchases to ensure that the workplace network environment is secure. However, in today's remote and hybrid work model, employees' computers are no longer always located in the company's controlled and secure network environment, but instead use public Wi-Fi networks in employees' homes or, for example, public spaces.
What does Zero Trust actually mean?
Zero Trust is not a product, a firewall, or a software package. It is a security philosophy and architecture built around a simple principle: Don't trust any user, device, or system – always check!
Even if the user is on your network. Even if the device looks familiar. Even if the login came from an employee.
Zero Trust is based on three core principles:
Continuous verification
• Continuously verify user identity, device health, location, and operation
Don't share more rights than you have to
• Users and applications only receive the minimum access needed – nothing more
Assume a data breach occurs
• Design systems as if attackers were already inside
• Limit the scope of the attack and monitor everything
Why should you implement Zero Trust immediately?
Identity Attacks Now Dominate the Threat Landscape
- Attackers no longer waste time exploiting firewalls – they steal credentials, break MFA,
or impersonate employees with AI-generated content
Artificial intelligence helps both attackers and defenders
- Generative AI tools can create near-perfect phishing messages
- Deepfakes for audio and video attacks specifically target leaders
- Autonomous AI functions scan environments for misconfigurations
- Zero Trust limits what attackers can do, even if they get in
Hybrid and remote work expanded every company's attack surface
- Unmanaged devices, personal laptops, and remote networks mean,
that the “inside the office = safe” assumption no longer works
The spread of cloud and SaaS services is uncontrolled
- Organizations use dozens of cloud applications, and each of them is an entry point
- Zero Trust ensures that every request and connection is confirmed
Supply chain data breaches are on the rise
- A weak supplier can compromise the entire company. Zero Trust helps isolate systems,
so that one vulnerable partner doesn't jeopardize everything
Regulatory pressure is increasing
- Governments and standards bodies are increasingly recommending or requiring Zero Trust principles in modern cyber security programs
How does Zero Trust reduce damage?
Let's think about a typical ransomware attack:
→ Attacker steals employee credentials
→ Logs into VPN
→ Moves laterally within the network
→ Encrypts servers and leaks data
When Zero Trust architecture is in use:
→ Logging in would require stronger identity checks
→ The device may be marked as non-compliant
→ Lateral movement is prevented by micro-segmentation
→ Behavioral analytics detects unusual usage patterns
→ The scope of the attack is limited to one small segment
→ Instead of a company-wide outage, you get a managed event
What do companies that adopt Zero Trust architecture gain?
- More effective information security
- Better prepared to comply with different requirements frameworks
- Secure access to business-critical applications and data from anywhere, anytime
- Real-time protection for network traffic, filtering malicious traffic and blocking unwanted threats
- Intelligent, real-time user protection management reduces latency and reduces attack surface
- Cloud-based, offers full scalability, enabling organizational growth
- Reduces the number of security solutions, leading to lower IT costs and simpler management
Why is Zero Trust worth implementing right away?
Zero Trust is no longer “the future of cybersecurity.” It’s the minimum standard for secure operations. Cybersecurity threats in 2026 will be more sophisticated, automated, and identity-centric than ever before. Zero Trust is not a buzzword—it’s a survival strategy. Companies that adopt it now won’t just be safer, they’ll be stronger, more agile, and more competitive for years to come.
How can we help?
We provide corporate information security consultations & surveys, for example on the following areas: corporate information security, firewalls, secure remote working (SASE, Cato Networks), M365 environment and its information security, data center services, monitoring systems, as well as vulnerability assessments and system assessments.
