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.
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

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

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
Products using it
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
Products using it
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
Products using it
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.
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
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
