What we provide

Eight data streams, one distribution point

SignGuard provides eight kinds of data to the products; each stream is collected from its own sources, verified, signed and published as a release. Below is what you receive and which product uses which stream.

01

Web content categories

11 million+ domains · 63 categories

More than eleven million domains are classified into 63 categories: from malware and phishing to gambling, from adult content to social media and business applications. The categories sit in five groups — security threats, legal liability, adult and sensitive content, bandwidth, business and productivity. A product binds the rule to the category rather than to the domain, so a site that did not exist yesterday falls under the right rule today.

What it includes

  • Domain and URL classification
  • 63 content categories in five groups
  • Subdomain and parent-domain matching
  • Continuous updates for new and changed sites
  • Miscategorisation reports and a correction process

02

Application identification

2,000+ applications · 50,000+ signatures

More than two thousand applications are recognised through over fifty thousand signatures, independently of the port in use. Without this, a rule such as “throttle video streaming during work hours” cannot be written at all, because most modern applications travel through the same door under the same encrypted protocol.

What it includes

  • Port-independent application identification
  • Application categories and risk levels
  • Behavioural matching on encrypted traffic
  • Support for bandwidth and time-based rules

03

Intrusion prevention signatures

80,000+ active signatures · 55 categories

More than eighty thousand active attack signatures are maintained across fifty-five categories. A significant part of them comes entirely from our own research: we produce, verify and refresh our own indicators for command-and-control infrastructure, malware distribution points and mining networks. Stale records are retired, because a false alarm costs as much as a missing record.

What it includes

  • Known vulnerability and attack patterns
  • Command-and-control (C2) infrastructure indicators
  • Malware distribution and mining networks
  • Record ageing and withdrawal

04

Country and IP reputation

250+ countries and regions

Current address ranges for more than two hundred and fifty countries and regions, together with attacker, scanner, anonymiser, command-and-control and spam-source address sets. Geographic restrictions and reputation-based decisions run on this data: you can tell whether a login attempt came from the office or from behind an anonymiser.

What it includes

  • Country and region address ranges
  • Attacker and scanner address sets
  • Anonymiser, proxy and exit-node lists
  • Spam-source and poor-reputation blocks

05

Device identification

58,000+ vendor records

With more than fifty-eight thousand vendor records and our own fingerprint tables, the device joining the network is identified: phone, computer, printer, camera, smart-home device. Different policies can then apply to different device classes; a guest phone need not be governed by the same rules as a camera.

What it includes

  • Vendor (OUI) and model mapping
  • Device-type fingerprints
  • Policy support by device class
  • Guest and corporate device separation

06

Internet service addresses

Current address ranges published by the vendors of common cloud and business services are collected and delivered to the products. Rules such as “allow this service” or “allow only this service” therefore do not break silently when a provider changes its addresses.

What it includes

  • Cloud and business service address blocks
  • Vendor-sourced, verified lists
  • Change tracking and automatic updates
  • Ready-made sets for allow-list rules

07

Anti-spam

3,000+ content rules

More than three thousand content rules and sender reputation sets are provided for mail traffic. Rules are delivered in structured form and scored by the product’s own engine. Which score leads to which action — tag, quarantine, reject — is your decision.

What it includes

  • Content and header rules
  • Sender reputation sets
  • Phishing and spoofed-sender indicators
  • Structured rule delivery; scoring in the product

Products using it

08

File reputation

1 million+ fingerprints

More than one million known malicious file fingerprints are maintained. Whether a downloaded file — or one entering a backup — has previously been recorded as malicious is checked instantly. The file itself is never sent to us; only the fingerprint is compared.

What it includes

  • Known malicious file fingerprints
  • Indicators for ransomware families
  • Local comparison; the file never leaves
  • Daily refreshed record set

Also

Two more streams that keep the product current

Alongside the main eight, two further distributions travel the same line to keep the product’s rule set and software up to date.

Classification rules and policy templates

Sensitive-data patterns such as identity numbers, card numbers and health records, together with matching ready-made policy templates, are distributed under a version number. When regulation changes the template is updated; the organisation does not rewrite its rule set.

  • Sensitive-data patterns (identity, card, health, financial)
  • Ready GDPR and KVKK policy templates
  • Versioned, traceable distribution
  • Works alongside your own rules

Software updates

Product software, fix packages and component updates are published from the same distribution point. A product learns about a new release through SignGuard and downloads it only after verifying the signature. The update screen shows which version was installed and when.

  • Release and fix packages
  • Component and dependency updates
  • Cryptographic signature and integrity check
  • Links to release notes

The category list is public
