CE vs. Pro: What Is the Difference?

Understanding the differences between editions helps you decide when to upgrade.

Feature Comparison

|---------|-------------------|--------------|------------|

| Collaboration | No | Yes | Yes |

| Local Transforms | Yes | Yes | Yes |

| Custom Transforms | Yes | Yes | Yes |

| Active Directory | No | Yes | Yes |

| LDAP Integration | No | Yes | Yes |

Key Limitations of CE

**Graph Size Limits**: CE restricts the number of entities on a graph to 10,000. For most individual investigations, this is sufficient, but large-scale infrastructure mappings may hit this limit.

**Transform Limits**: Not all transforms from the Transform Hub are available in CE. Premium transforms from commercial data providers are restricted.

**Result Limits**: Some transforms return fewer results in CE compared to paid editions. For example, a subdomain enumeration transform might return the top 50 results instead of 500.

**No Collaboration Features**: CE does not support shared workspaces or multi-user collaboration.

**Limited Reporting**: Advanced report generation and templating features are restricted to paid editions.

Available Transforms in CE

Despite its limitations, CE provides access to a substantial set of transforms that cover most common OSINT needs.

Built-in Transforms

Maltego CE includes several categories of built-in transforms:

DNS and Network Transforms:

Domain to DNS Name

Domain to MX Record

Domain to NS Record

Domain to IP Address

IP Address to Domain

IP Address to Netblock

Person and Email Transforms:

Person to Email Address

Email Address to Person

Domain to Email Address

Website Transforms:

Domain to Website

Website to HTML Content

Website to Title

Free Hub Transforms

The Transform Hub includes several free transform sets that work with CE:

| Transform Set | Data Source | What It Finds |

|---------------|-------------|---------------|

| Maltego Built-in | Various | DNS, WHOIS, basic lookups |

| Shodan | Shodan.io | Open ports, services, banners |

| Have I Been Pwned | HIBP | Breached email addresses |

| VirusTotal | VirusTotal.com | Domain/IP reputation |

| crt.sh | Certificate Transparency | SSL certificate subdomains |

| Wayback Machine | Internet Archive | Historical web content |

Setting Up API Keys

Many free transforms require API keys. Here is how to configure them:

Getting the Most from CE

Strategy 1: Combine Free Tools

Since CE has transform limitations, combine it with other free OSINT tools:

**theHarvester**: Gather emails, subdomains, and names before importing into Maltego

**Amass**: Deep subdomain enumeration with OWASP's Amass

**Recon-ng**: Modular reconnaissance framework

**SpiderFoot**: Automated OSINT collection

Workflow Example:

Run theHarvester against a target domain

Export results to CSV

Import the CSV into Maltego

Use Maltego's transforms to expand and visualize findings

Strategy 2: Manual Entity Creation

When transforms are limited, manually add entities:

Drag an entity type from the palette

Double-click to edit its value

Add properties by right-clicking and selecting **Edit Properties**

Run available transforms on manually created entities

Strategy 3: Strategic Transform Selection

Not all transforms are equally useful. Focus on high-value transforms:

**Certificate Transparency (crt.sh)**: Often finds subdomains that DNS enumeration misses

**Shodan**: Reveals open services and potential vulnerabilities

**WHOIS**: Provides registration details and historical data

**Wayback Machine**: Uncovers historical content and hidden directories

Strategy 4: Graph Segmentation

When approaching the entity limit:

Save your current graph

Create a new graph for the next phase of investigation

Use entity notes to cross-reference between graphs

Export both graphs to CSV and merge in a spreadsheet for analysis

Strategy 5: Custom Transforms

CE supports custom transforms via the TREST API. You can:

Write transforms in Python using the Maltego Python library

Connect to your own data sources

Process results locally

Share custom transforms with your team

Step-by-Step: Complete CE Investigation

Let's walk through a complete investigation using only CE and free tools.

Phase 1: External Reconnaissance

Tools: theHarvester, Amass

# Run theHarvester for initial discovery
theHarvester -d target.com -b all -f harvester-results.html

# Run Amass for deep subdomain enumeration
amass enum -passive -d target.com -o amass-results.txt

Phase 2: Import into Maltego

Open Maltego CE

Create a new graph

For each discovered subdomain:

- Drag a DNS Name entity onto the graph

- Enter the subdomain value

For each email address:

- Drag an Email Address entity

- Enter the email

Phase 3: Expand with CE Transforms

Select all DNS Name entities

Run **To IP Address** transform

Select resulting IP addresses

Run **To Netblock** transform

Run **To ASN** transform on IPs

Phase 4: Service Discovery

Select IP addresses

Run **Shodan IP** transform (requires API key)

Review discovered services and banners

Note any interesting findings

Phase 5: Certificate Analysis

Select the root domain

Run **To Certificate (crt.sh)** transform

Review certificate results for additional subdomains

Add any new subdomains to the graph

Phase 6: Analysis and Documentation

Apply graph layout (Organic works well for network maps)

Color-code entities by type or finding

Add notes to important entities

Export the graph as PDF for your report

CE Limitations Workarounds

Hitting the 10,000 Entity Limit

Solution: Split your investigation into multiple graphs organized by:

Subdomain groups (e.g., by IP range or function)

Investigation phase (reconnaissance, enumeration, analysis)

Target type (infrastructure, people, services)

Transform Returning Too Few Results

Solution: Use multiple data sources:

Run crt.sh for certificate transparency data

Run Amass passively for additional subdomains

Combine results before importing into Maltego

No Access to Premium Transforms

Solution: Use free alternatives:

| Premium Transform | Free Alternative |

|-------------------|------------------|

| DomainTools WHOIS | WHOIS lookup via command line |

| ZoomEye | Shodan (free tier) |

| RiskIQ | SecurityTrails (free tier) |

| Full Contact | Manual LinkedIn research |

Limited Reporting

Solution: Export and use external tools:

Export graph as CSV

Import into Google Sheets or Excel

Create charts and pivot tables

Generate custom reports

When to Upgrade to Professional

Consider upgrading when:

You frequently hit the 10,000 entity limit

You need transforms from premium data providers

You require collaboration features for team investigations

You need advanced reporting and templating

You are conducting commercial security assessments

You need API access for automation

Conclusion

Maltego Community Edition is a remarkably capable free tool that provides genuine OSINT and link analysis functionality. While it has limitations compared to paid editions, creative use of free transforms, manual entity creation, and integration with other OSINT tools can compensate for most gaps.

The key to maximizing CE is understanding its constraints and working within them strategically. Start with CE, master the fundamentals, and upgrade only when your specific use case demands it. For most individual researchers and students, CE provides more than enough capability to conduct meaningful investigations.

Remember that the value of OSINT comes from methodology, not just tools. A skilled analyst with CE can produce better results than an unskilled user with Enterprise. Focus on developing your investigative skills alongside your technical capabilities.
