Notes on open source IT, ERP and AI automation
Practical takes from our own deployments — no generic listicles.
Why our SaaS offers are becoming Trusteco building blocks, right here on trustiatis.com

Costs & ROI2026-06-30Vendor lock-in: how to spot it before you sign, not after
Vendor lock-in almost never shows in the initial contract. Here are the 5 questions to ask a vendor before committing, to avoid a bad surprise on your way out.
Collaboration2026-09-01Jitsi Meet: self-hosted video conferencing, no third-party account
No participant cap set by a vendor, no account for your clients to create, no meeting data passing through a third party. What Jitsi Meet actually changes once self-hosted.
Collaboration2026-09-01Matrix and Element: team messaging that actually belongs to you
Matrix is a protocol, not a product — Element is its most widely used interface. What makes the combination relevant for a business: end-to-end encryption and decentralization.
Collaboration2026-09-01Thunderbird: professional email that stays under your control
A mature open source mail client, maintained by the Mozilla Foundation, compatible with any IMAP/SMTP server — including your own. What matters for a business isn't the client, it's where the mailbox actually lives.

Why we orchestrate several agent backends instead of one, and where OpenAI naturally fits in an n8n architecture.
Artificial intelligence2026-09-01Z.ai and GLM models: a credible alternative for agentic work
Z.ai (Zhipu AI) publishes the GLM model family, with open weights on several versions. What that actually changes for hosting an agent yourself instead of on a third party's infrastructure.
Cybersecurity2026-09-01AI agents and cybersecurity: the new habits to build
An agent that can read your repositories, run commands and call external tools is a new attack surface, not just a new tool. What to check before granting it access.
Cybersecurity2026-09-01Phishing and social engineering: what's changed with generative AI
Spelling mistakes and awkward phrasing are no longer reliable signals. What still holds up as a solid indicator when facing a suspicious email or call.

Free, no commitment — but concretely, what do we look at, how long does it take, and what do you get at the end?
Cybersecurity2026-09-02The 3-2-1 rule: backups that actually protect your data
A backup on the same server as the original data isn't a backup, it's a copy. The simple principle that tells the two apart.
