Farm data is valuable - it includes information about soil moisture, crop yields, and field locations. But if this information falls into the wrong hands, it could be used against farmers: competitors could steal business strategies, hackers could hold data hostage, or personal information could be misused.
At KhawTech, our NaLog software isn’t just about providing irrigation insights - it’s designed as a secure fortress for your data. We process most information locally on the farm (not in the cloud), use strong encryption that can resist even future quantum computers, and ensure farmers always own their own data.
With Thailand’s Personal Data Protection Act (PDPA) becoming stricter, we’ve built security into every aspect of our system. Farmers in our Yasothon cooperatives have been using NaLog for over 3 years without any data breaches. For cooperatives considering technology but worried about privacy, here’s how we keep your information safe: end-to-end encryption, local control, and full legal compliance. We earn trust through proven security, because farmers need to feel confident that their data serves them, not someone else.
Why Farm Data Security Matters
IoT sensors collect valuable information: exact field locations, harvest timing, water usage patterns. If this data gets compromised, the consequences could be serious. Competitors might copy successful farming strategies, hackers could demand ransom to restore access to cooperative systems, or personal information could be exploited.
Thailand’s Personal Data Protection Act (PDPA), introduced in 2022, requires companies to get consent for data collection and protect personal information. In rural areas with unreliable internet, these risks are even higher because it’s harder to monitor and respond to threats.
Our approach at KhawTech is to design for security from the beginning. We don’t just say “trust us” - we show you the protections we’ve built. Our sensor networks have operated for over 3 years without a single data breach, and we conduct annual security audits.

How We Encrypt Data from Field to Dashboard
Your farm data is protected with multiple layers of encryption at every step:
-
At the sensor: Information sent via LoRa radio is encrypted using AES-128 standard. Each device has unique security keys that we rotate annually.
-
During transmission: Gateways use TLS 1.3 encryption (quantum-resistant) to send data to NaLog. When internet is unavailable, data is stored locally in an encrypted database.
-
In storage: Data in our cloud (hosted on AWS) is encrypted at rest using AES-256. We don’t store raw sensor readings - only anonymized summaries for analysis.
-
For access: We use role-based permissions - individual farmers only see data from their own fields. Cooperative administrators can view group data, while investors get summary reports only. Two-factor authentication is required, and all access is logged.
For example, when a moisture sensor in Yasothon detects dry soil, it sends an encrypted signal to the gateway, which decrypts it, processes it, and sends it securely to NaLog. Even if someone intercepted the transmission, they would only see gibberish.
Unlike some other IoT systems we’ve seen in Southeast Asia that send data unencrypted, our approach has resulted in zero security incidents and is ready for future threats from quantum computers.
You Own Your Data - We Don’t Sell It
Privacy means you control your own information - you own the story of your fields.
-
Local processing first: 90% of data analysis happens on the farm gateway itself, so information stays in your community. Data only syncs to the cloud when you explicitly opt in, and then in secure batches.
-
No data sales: We don’t sell or monetize farmer data. Our revenue comes from software subscriptions, not from advertising or data profiling.
-
Granular consent: The app gives you clear choices - “Share your yield data with the cooperative?” or “Allow access for carbon credit verification?” You can revoke permissions anytime, fully compliant with PDPA requirements.
-
Full control: You can export your data or delete it completely at any time, with a complete audit trail of who accessed what and when.
For example, a cooperative in Ubon shares aggregated water savings data to qualify for government grants and carbon credits, but individual farmer data remains private and secure. One farmer told us: “My field’s data belongs to me - KhawTech helps me use it, but they don’t own it.”
We pass regular PDPA compliance audits and are working toward ISO 27001 certification. Our secure data handling also enables trustworthy reporting for Verified Carbon Standard credits.
How We Build and Maintain Trust
Security isn’t just about technology - it’s about people and processes:
-
Regular audits and training: We conduct annual penetration testing and hold cooperative workshops on recognizing suspicious activity.
-
Quick response to issues: We have a 24-hour service level agreement for security incidents, with remote fixes through secure connections. We didn’t lose any data during the 2024 floods.
-
Transparency reports: Cooperatives receive quarterly updates showing security metrics and confirming zero breaches.
-
Open standards: Our system integrates with open-source tools and provides auditable APIs.
The challenge in rural areas is often digital literacy, which we address with voice-guided interfaces and simple training. Looking ahead, we’re exploring blockchain technology for immutable audit logs.
In Isan communities, trust is essential for technology adoption. Our low customer churn rate comes from delivering reliable security that farmers can depend on.
Protecting Farmers, Enabling Innovation
NaLog’s security features allow farmers to confidently adopt new technologies - privacy is built-in from the start, not added as an afterthought.
