An AI shield against email attacks
DeepFilter catches phishing, ransomware and targeted fraud with a multi-layered defense and quarantines them. 99.44% precision in our own AI model. It runs entirely on your own servers, with a fully Turkish and English management console; your email content never goes to a third-party cloud.
Attacks begin with email
Superior protection that instantly recognizes today's AI-assisted attacks targeting your corporate addresses.
Phishing & BEC
Impersonation of brands, couriers, banks and government services; executive fraud. Locally-curated content rules catch region-specific campaigns.
Ransomware & malicious attachments
A single malicious attachment can encrypt your organization's entire file base. Effective defense against zero-day attacks with real-time signature updates.
Image-based spam
When attackers hide text inside images to slip past text filters, DeepFilter catches them by recognizing visually similar images.
Four stages, one trust score
Dozens of signals combine into a single trust score; every decision is transparent.
Pre-Analysis
The sender and the message pass a first screening across authentication, blocklist and statistical classification layers within seconds.
Deep Inspection
AI, central intelligence, signature matching and visual inspection layers examine the message in depth.
Evaluation
Scores from every layer combine into one trust score; the mail is classified as clean, suspicious or dangerous.
Decision
Email that clears the trust threshold is delivered to the recipient; the rest is quarantined.
The control the cloud can't give you
The choice of organizations seeking a next-generation email shield with layered deep filtering, far beyond traditional anti-spam scanning.
Independent AI Model
An AI model trained on 200,000+ emails, running on your own server, with 99.44% accuracy.
Your data stays with you
Your routine email traffic and email content never leave your organization's boundary; it supports your GDPR/KVKK compliance.
Native-language management
Native-language admin console, end-user portal and a 400+ rule explainable score knowledge base. With local support whenever you need it.
National threat intelligence
Regional threat-intelligence pack: national cyber-security authority feed (Türkiye), integrated with signature and integrity verification.
Collective intelligence, without sharing your data
You run locally, but you are not alone: through the central intelligence network every deployment talks to the others and blocking happens instantly. This intelligence network is protected with advanced encryption and a dedicated hashing mechanism.
Region-specific DLP
Detects region-specific data patterns (e.g. national ID, IBAN, card numbers) in outbound mail to help prevent data leaks (optional module).
Not one filter — seven layers deep
Inside these four stages, seven technology layers do the work: SPF/DKIM authentication and scenario-based policy, blacklist queries, statistical classification, AI-assisted detection, similarity analysis, antivirus and phishing detection. They all combine into one trust score; borderline mail is flagged as "suspicious".

Everything you need for corporate email security
Beyond the headline differentiators: 12 standard tools your team uses every day — content filtering, authentication, reporting and quarantine.
Content & subject filtering
Block banned words and subject patterns.
URL / link blocking
Block malicious or unwanted links in the body.
Dangerous file-type blocking
Block executable/risky attachments — inbound and outbound.
SPF/DKIM authentication
Authentication results with scenario-based policy.
Quarantine digests
Daily/weekly digests; users manage their own quarantine.
Scheduled exec reports
Scheduled HTML/PDF reports to multiple recipients.
IP reputation monitoring
Your IPs are monitored periodically across current DNSBLs.
Granular allow / block
Flexible allow/block policies per domain, sender, recipient.
Flexible placement
Sits in front of M365, Workspace, Zimbra, Exchange or your SMTP services.
Signatures stay intact
Inspects signed mail without altering it; encrypted content is left untouched — signatures stay valid.
Fail-open resilience
If one filter fails, the others keep protecting you.
Quarantine management
Admin filters/audit + end-user self-service portal.
Every decision comes with an explanation
For every triggered rule: what it is, why it fired, the matched value and its contribution to the score — in clickable cards. A 400+ rule knowledge base in both languages. Not a black box.
