Data Classification Guide
A research guide explaining what data classification is, why it matters, how it works, and how organizations can implement it effectively.

Aziz Ortanc
Senior Cyber Security Engineer
I design and operate enterprise DLP and data protection deployments - endpoint, network, and CASB. I know the full product landscape: classification engines, discovery logic, policy enforcement, and vendor capability mapping. I also advise teams evaluating DLP, data classification, and data discovery products through requirement analysis, vendor capability mapping, PoC scope design, and fit recommendations based on real deployment constraints.
What I Specialize In
A compact view of the work: from data protection controls to the infrastructure and enablement practices that make them usable.
Data Protection / Product Intelligence
Deep DLP, data classification, data discovery, and CASB knowledge; able to read requirements, compare vendor capabilities, recommend product fit, and identify validation points.
Infrastructure / Traffic Analysis
Comfortable across Windows/Linux services, directory and network foundations, security data platforms, firewall flows, and packet-level troubleshooting.
Implementation, Automation, Prototyping
Bridges hands-on implementation with scripting, documentation, customer enablement, and fast side-project prototyping.
Engineering Habits
[01]
Start With the Problem
Good technical work starts with analysis, research, evidence, and a clear definition of what needs to be solved.
[02]
Understand the Flow
Inspection is safer when the protocol, queue, timeout, and failure path are understood before rules are added.
[03]
Design for Bad Days
Security systems need predictable behavior during load, outages, updates, and partial failures.
Operating Notes
- Start with evidence before touching configuration.
- Design controls with latency, recovery, and ownership in mind.
- Keep automation readable enough for the next incident.
- Turn complex systems into clear handover notes.
Technical Skills
A practical map of the areas I use while building, deploying, and troubleshooting security controls.
Security / Product
DLP families, classification/discovery, CASB controls, mail gateway behavior, requirement review, and product fit analysis.
Infrastructure / Data
Windows domain services, Linux and Windows servers, MongoDB and ElasticSearch clusters, hardening, recovery, and troubleshooting.
Analysis / Enablement
Packet analysis, protocol tracing, Bash and PowerShell tooling, customer enablement, documentation, and rapid prototypes.
Selected Notes
Short technical writing on data protection products, infrastructure troubleshooting, protocol analysis, and security engineering practices.
