Parallel multi-search
Execution of up to 10 queries simultaneously with single search performance.
Convenient technology for mass verification of credentials and complex investigations.

Practical scenarios:
Email list verification — upload 10 addresses and get results in seconds
Infrastructure analysis — simultaneous verification of IP ranges and domains
Credential stuffing audit — mass verification of credentials for pentest
Incident response — quick verification of multiple IoCs during incident investigation
OSINT investigations — parallel search by different target identifiers

Technical details:
Maximum 10 queries in one multi-search
Up to 2,000,000 rows per each query
Total limit 20,000,000 rows at maximum configuration
Single export — all files in one archive with separation by queries
Speed — execution time slightly increases with number of queries

Usage example:
Query 1:
*company[.]com (wildcard, 100K rows)
Query 2: 192.168.1.* (wildcard, 50K rows)
Query 3: admin@* (wildcard, 200K rows)
Query 4-10: specific *email* (wildcard, 10K rows each)
Result: all data in one execution, total quota consumption ~370K
Basic search
Platform foundation — fast and accurate search by any data field.
From simple emails to complex regex patterns — all in one interface.

Available search fields:
URL
— full addresses of compromised resources
E-MAIL — email addresses with domain-based search
USERNAME — user logins and nicknames
PASSWORD — passwords in clear-text or hashed form
PHONE NUMBER — phone numbers in various formats
IPv4 — IP addresses for network forensics
HOSTNAME — computer and server names
OS USERNAME — local OS accounts
NAME — full user names
CARD — bank card data
LOGIN — universal field for various identifiers
DOMAIN — domain search (finds all URLs with this domain)

Search methods:
• Exact Match
— exact match for known values. Maximum speed and accuracy
• Wildcard — flexible patterns with * and ? for mask search. Perfect for domains and ranges
• Regex — full power of regular expressions for complex patterns and validation

Practical application:
• Pentesting
— verification of compromised organization credentials
• OSINT — gathering information about target through various identifiers
• Incident Response — quick IoC verification during incident investigation
• Threat Intelligence — monitoring breaches by key parameters
• Compliance — data exposure audit for regulatory requirements
Analysis of connections between records
One of the key tools of the platform — automatic building of connection maps between accounts.
One email → username → another email → shared password. The system finds chains itself.

How it works:
Algorithms analyze billions of connections between records, identifying patterns:
Shared passwords between different accounts
Similar usernames and name variations
Related emails through domains and aliases
Same IPs and infrastructure markers
Temporal correlations — accounts created at the same time
Behavioral patterns — similar user actions

Intelligent assessment:
Not all matches mean a real connection. The system uses a scoring model:
High confidence (80-100%) — direct connections through unique data
Medium confidence (60-80%) — multiple indirect matches
Low confidence (40-60%) — weak correlations, require verification

Configurable depth:
Depth 1-2 — direct connections, fast and accurate
Depth 3-4 — extended networks, balance of speed and coverage
Depth 5+ — complete mapping, maximum detail

Practical application:
• OSINT investigations
— building complete target profile through connections
• Threat Intelligence — identifying threat actor infrastructure
• Incident Response — determining scope of compromise
• Executive Protection — mapping digital footprint of VIP persons
• Fraud Detection — detecting related fraudulent accounts

Connection types:
Domains

Email variations
Infrastructure
Timestamps
Password patterns
Names and nicknames

Behavioral patterns
Visual query constructor
Industry-first
visual query builder for building most complex queries without SQL knowledge.
Drag-and-drop interface turns complex logic into intuitive visual blocks.

Revolutionary capabilities:
Visual building — drag-and-drop elements instead of writing syntax
Unlimited nesting — create complex condition hierarchies of any depth
Logical operators — AND, OR, NOT with visual grouping
Real-time preview — instant preview of query logic in natural language
Auto-optimization — engine automatically rewrites queries for maximum speed

Comparison operators:
Equals / Not Equals — exact match or exclusion
Contains / Not Contains — substring search within value
Starts With / Ends With — search by beginning or end of string
Greater / Less Than — comparison of dates and numeric values
Is Empty / Is Not Empty — checking for data presence in field
Regular Expression — full PCRE regex support for complex patterns

Practical scenarios:
Executive protection — (email contains "company[.]com" AND name contains "CEO") OR (username starts with "exec")
Incident response — (email contains "target[.]com" AND breachdate > "2024-01-01") AND NOT (username contains "test")
Threat intelligence — ((username contains "hacker" OR username contains "admin") AND password regex "^[A-Z]{2}[0-9]{4}$")
Compliance audit — (email ends with ".gov" OR address contains "Government") AND (identitynumber is not empty)

Technical advantages:
Query optimization — automatic reordering of conditions for speed
Index utilization — smart use of database indexes
Performance indicators — warnings about potentially slow queries
Nested logic support — up to 10+ nesting levels without performance loss
Natural language preview — clear description of query logic in human language

Complex query example:
AND Group (Root):

├─ email contains "company[.]com"
└─ OR Group (Level 1):
├─ password is not empty
└─ AND Group (Level 2):
├─ username starts with "admin"
└─ breachdate > "2025-01-01"

Result:
⁡[srci]⁡all company records with passwords OR admin accounts after 2025[/srci]
