About
İsmet Öztürk has more than 25 years in IT. He founded Xen Bilişim in 2016, which provides managed IT, cybersecurity, backup and cloud services to companies in Türkiye. His day job is picking the solution that fits the company rather than the one tied to a single manufacturer, then keeping it running.
On the Google side his focus is Google Workspace deployment and migration, email security (SPF, DKIM, DMARC), identity and device management, Google Cloud architecture and monthly cost control. He runs Microsoft environments at the same depth, which makes impartial advice possible in mixed estates.
The articles here favour concrete deployment decisions, Turkish invoicing and regulatory detail, and error fixes seen in the field over abstract transformation talk.
