ClassifyIt — Simple, Visible, Compliant 
Document & Email Classification for Outlook & Office
Protect your organisation's sensitive information with visible security markings and machine-readable metadata — applied consistently across Outlook, Word, PowerPoint, and Excel.
What Is ClassifyIt? 
ClassifyIt is a lightweight Office plugin that adds visual security markings and machine-readable metadata (JSON/X-Headers) to your documents and emails — helping your organisation comply with ISO 27001, GDPR, CUI, and other information security standards. It is easy to deploy, easy to use, and requires no complex infrastructure.
Key Features
- Compliance-ready — supports ISO 27001, GDPR, CUI, and custom internal frameworks
- Full Office integration — Outlook, Word, Excel, and PowerPoint
- Visible markings + embedded metadata — labels users can see and systems can process
- JSON/X-Headers — compatible with DLP tools, mail gateways, and archive systems
- Flexible deployment — on-premise, hybrid, or cloud
- Custom classification schemes — TLP, EU, NATO, Commercial, or your own
- Classifications as a Service — centrally managed, remotely updated
Why Choose ClassifyIt?
Unlike heavyweight DLP platforms, ClassifyIt is straightforward to roll out and simple for users to adopt. It delivers two layers of protection simultaneously: visible labels that raise user awareness, and embedded technical metadata that enables automated policy enforcement at the network boundary. Licensing is transparent, with no per-module fees or surprise costs.
Additional Tools
- CryptIt — encrypts email attachments and files using AES-256, with support for PIN-based and public-key encryption
- ClassifyIt Shell — a Windows Explorer extension for classifying and viewing the classification of any file directly in the file system
Pricing
A free version supporting the Traffic Light Protocol (TLP) is available for evaluation. Commercial licences start from €10 per user (volume pricing available). Each licence is perpetual, with an optional annual subscription for support and updates. If you are migrating from another classification tool, contact us — our motto is clear: "Don't pay twice for the same function."

How ClassifyIt Works 
ClassifyIt adds a stamp button directly into the ribbon of each Office application. When composing an email or working on a document, the user selects the appropriate classification from the ClassifyIt menu. The marking is then applied visibly to the document or email and stored as tamper-protected metadata — it cannot be changed or removed by the recipient.
Classifications are selected through a simple dropdown or a full selection form, depending on the complexity of your policy. Quick-select menus can be configured for the most commonly used markings.
Supported Classification Schemes
ClassifyIt supports any marking schema — simple or complex. Out of the box it works with:
- Commercial schemes (e.g. Public / Internal / Confidential / Secret)
- Traffic Light Protocol (TLP)
- EU and NATO classification markings
- Governmental markings including release and interoperability markings
- Any custom schema defined in your organisation's security policy
All markings are configured via a single JSON file, which can be stored on a web server, network share, or local drive — making central administration straightforward.
CryptIt 
CryptIt integrates with the same Office applications and adds file and attachment encryption to your workflow. Three encryption modes are supported: standard (built-in keys), PIN-based (shared by phone or other out-of-band channel), and public-key encryption using the recipient's certificate. All modes use AES-256.
ClassifyIt Shell 
ClassifyIt Shell extends Windows File Explorer to show classification icon overlays on files, and allows users to classify or inspect any file's classification directly — without opening the file in an Office application.
Latest Version
