AI is transforming HR. From drafting internal comms to planning change rollouts, it’s helping teams save time, structure thinking, and move faster.

But here’s the uncomfortable truth:

Most HR professionals have no idea where their AI data goes.

And that’s a problem.

Because HR doesn’t deal in harmless information.

You handle:

• Employee grievances
• Performance discussions
• Restructuring plans
• Leadership strategy
• Sensitive wellbeing cases
• Compensation discussions

That’s not casual content.

That’s high-risk organisational data.

Before using any AI tool for HR work, you need to ask one critical question:

Is this secure?

Why AI Security Matters More in HR

Unlike marketing or general admin, HR handles deeply personal and confidential data.

If sensitive information is:

• Stored without encryption
• Used to train models
• Accessible by unauthorised users
• Hosted in unknown jurisdictions

You’re exposed to legal, ethical, and reputational risk.

According to IBM’s 2023 Cost of a Data Breach Report, the average global data breach cost is $4.45 million,  the highest on record.

HR data is particularly damaging because it involves personal and employment-related information.

AI should reduce risk.
Not introduce new ones.

5 Questions HR Should Ask Before Using Any AI Tool

Here’s your practical checklist.

1. Is Our Data Stored, Or Ephemeral?

Does the tool:

• Permanently store conversations?
• Retain prompts after sessions end?
• Allow full deletion?

If you close the browser, is your data gone, or archived somewhere?

If it’s unclear, that’s a red flag.

2. Is Our Data Used to Train the Model?

Some AI tools use user input to improve their systems.

That may be acceptable for generic use.

But HR data should never quietly become part of a training dataset.

Always ask explicitly:
“Is our input data used to train your model?”

3. What Security Standards Do You Follow?

Look for recognised information security frameworks, such as:

• ISO 27001-aligned infrastructure
• SOC 2 compliance
• Encrypted cloud architecture
• Role-based access controls

If a vendor cannot explain their security model clearly and confidently, that’s concerning.

4. Where Is Data Stored Geographically?

Data jurisdiction matters.

Ask:

• Which country hosts our data?
• Is it stored within compliant cloud providers?
• Is it subject to GDPR protections?

For UK and EU HR teams especially, this is critical.

5. Can We Delete Everything Permanently?

You should be able to:

• Delete conversations
• Remove stored data
• Close accounts without lingering archives

If deletion is unclear or complex, that’s not best practice.

What Thesmia Does Differently

We built Thesmia specifically for HR teams.

That means security wasn’t an afterthought.

It was foundational.

💜 Free Version: Browser-Based, No Data Storage

When you use Thesmia’s free version:

• Conversations are not stored server-side
• Data remains within your browser session
• Close the tab, the session is gone

No retained chat history.
No hidden archives.

Think of it as strategic AI in incognito mode.

💎 Account & Pro Versions: Secure Infrastructure

For registered users and Pro subscribers:

• Data is stored securely using ISO 27001-aligned cloud infrastructure
• Encrypted at rest and in transit
• Access-controlled environments
• Built with recognised security best practices

We do not use your organisational data to train open AI models.

Because HR deserves grown-up technology.

Not hobbyist platforms.

AI Should Make You Powerful, Not Nervous

AI isn’t the enemy.

Blind adoption is.

HR professionals are guardians of some of the most sensitive data in any organisation.

You should:

• Ask hard questions
• Demand clarity
• Expect transparency

Secure AI lets you innovate confidently.

And sleep at night.

Final Thought

Good AI makes you faster.
