Hybrid work has expanded the attack surface for ransomware, especially as employees rely on laptops outside the protection of office firewalls. In this environment, devices that move between networks and locations need more than a conventional antivirus layer.
In Indonesia, the concern is already visible. BSSN reported that around 83.68 percent of all cyber anomalies detected in the country were dominated by malware attacks, while newer variants such as The Gentlemen and SystemBC have been described as using AI to operate more independently.
Why the laptop itself has become the first line of defense
Security no longer starts with the office network alone. For hybrid workers, the laptop is now the place where identity, data access, and daily productivity meet, which makes built-in protection a critical requirement.
That is why five device-level features deserve close attention before a laptop is trusted for work across public Wi-Fi, shared spaces, and changing locations.
1. Zero Trust protection at the device level
Traditional security models that assume an internal network is safe no longer fit hybrid work. Modern laptops should support Zero Trust architecture that verifies every access attempt and every identity with strict checks at all times.
This matters because stolen credentials from phishing do not automatically give attackers full control over the operating system or the wider device ecosystem.
2. AI-driven endpoint protection
Signature-based antivirus tools are often too slow to respond to automated attacks. Laptops should ideally include Endpoint Protection Platforms supported by AI so suspicious file behavior can be analyzed in real time.
Such protection can spot unusual activity, including sudden mass encryption, and isolate it before ransomware locks important documents.
3. Automatic end-to-end data encryption
Another layer of defense comes from encryption that runs automatically on the laptop’s local storage. This becomes especially important on unsecured Wi-Fi, such as when work happens in a café or other public place.
With encryption active, sensitive data remains difficult for third parties to read both in transit and at rest on the device.
| Feature | Core Function | Benefit for Hybrid Workers |
|---|---|---|
| Zero Trust | Strictly verifies access and identity | Helps prevent full takeover after credential theft |
| AI-Driven Endpoint Protection | Analyzes file behavior in real time | Detects mass encryption faster |
| End-to-End Encryption | Protects data in storage and during transfer | Keeps data harder to read on public Wi-Fi |
| Automatic Patch Management | Installs security and firmware updates | Closes old vulnerabilities that are often exploited |
| Next-Generation Firewall | Filters incoming and outgoing traffic | Blocks dangerous connections and intrusion attempts |
4. Automatic patch and firmware updates
Many attacks succeed not because defenses are absent, but because security updates are ignored. That is why automated patch management should stay active on any laptop used for work.
By 2026, attackers are said to be increasingly willing to exploit old security flaws that already have official fixes from operating system developers.
5. A local next-generation firewall
Laptops that travel often need a defense layer that works on its own. A built-in next-generation firewall can filter inbound and outbound traffic, detect network intrusion attempts, and block malicious domains linked to malware distribution.
The threat environment is also changing in form, moving from simple data locking to double and triple extortion that targets institutional reputation. In that context, techno.viva.co.id highlighted the importance of combining user awareness with device-level technology, including the push toward centralized security automation from solution providers such as Fortinet.
For hybrid workers, checking these five features on a work laptop is a practical first step. As AI-powered ransomware becomes more aggressive, device security is no longer an optional extra but a basic requirement for keeping productivity running.
