On-Premise · AI-Assisted Email Security

An AI shield against email attacks

Regional Threat Intelligence Native-Language Support Expert Support
The Threat

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.

How does it work?

Four stages, one trust score

Dozens of signals combine into a single trust score; every decision is transparent.

01

Pre-Analysis

The sender and the message pass a first screening across authentication, blocklist and statistical classification layers within seconds.

02

Deep Inspection

AI, central intelligence, signature matching and visual inspection layers examine the message in depth.

03

Evaluation

Scores from every layer combine into one trust score; the mail is classified as clean, suspicious or dangerous.

04

Decision

Email that clears the trust threshold is delivered to the recipient; the rest is quarantined.

Why DeepFilter?

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).

Detection layers

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".

All the tools

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.

Transparency

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.

On-Premise

Not the cloud — your own server

DeepFilter · On Your Own Server

lokal
  • Email content is processed inside your facility, not a third-party cloud
  • One-click install and updates from the panel
  • A single server handles from 1,000 up to 500,000 emails/day; scales horizontally to millions
  • Data location and control stay with you — data-residency-aware

Cloud-based gateway (SEG)

  • Email content is usually processed in off-site / overseas data centers
  • Local-language campaigns and regional threats are often an afterthought
  • Data location and sovereignty stay under the provider's control
  • Public-sector / regulatory needs require extra assessment

FAQ

Frequently asked questions

Is it compatible with my existing email infrastructure?
Yes. DeepFilter sits as an email security gateway in front of your existing email infrastructure; it scans incoming traffic and delivers clean mail to your server.
Is my data shared with you?
Your routine email traffic is processed inside your organization's data center and stays there.
How does the AI service work?
The AI model, trained on 200,000+ emails, is downloaded to your server during initial setup and scans your email traffic directly on your own server. The model is periodically retrained with new data and rolled out after testing.
Where does it stand on KVKK/GDPR?
DeepFilter is designed with KVKK/GDPR in focus; your data is processed in your own country, inside your own facility. It provides the transparency and audit records to support your compliance assessment.
How do installation and licensing work?
Installation completes in a single step in 6 minutes with the installer package. Licensing is based on scanned emails/day, not per mailbox; special discounts are available for public sector, education and non-profits.
What does the demo/POC involve, and is it free?
The POC is free. We run the installation and the demo end-to-end on your existing infrastructure; you simply evaluate the results. After your request, our specialists plan the process with you.
What happens if I exceed my license?
Exceeding your licensed volume causes no downtime and no disruption to your mail traffic.
Can I purchase a multi-year license?
The first year is available as a 1-year license only; for the following years you can choose between 1, 2 or 3-year options.
Can I use my license on multiple servers?
No, each license runs on a single server. If you need more than one server, contact our sales team.
How is support provided?
Local expert support is provided during business hours. With an optional 24/7 support package, you get uninterrupted phone and email support.
What is the false-positive rate?
With accuracy improving every day, the false-positive rate stays below 0.1%.
Can end users manage their own quarantine and whitelist?
Yes. With digest emails sent at the frequency the administrator sets, users stay informed about their quarantined emails and can release them. They can also whitelist senders so those emails are delivered without ever being held.
How does it catch spam and phishing?
Custom content rules (impersonation of banks, couriers and government services) work together with national threat intelligence and similarity analysis; regional campaigns are caught where global products miss them.
