Fidelis Active Directory Intercept™
Stop Identity Attacks Before They Reach Your Domain Controller
Fidelis Security® has been Protecting Leading Enterprises Worldwide for over 20 years
When Attackers Target AD, They Target Your Entire Organization
Active Directory is the gateway to every system, every user, and every credential in your enterprise. These organizations chose Fidelis Active Directory Intercept™ because a single compromised privileged account or misconfigured trust relationship is all it takes for an attacker to achieve full domain control.

How Fidelis AD Intercept™ Outsmarts Attackers
Comprehensive AD Protection Across Every Attack Vector
Respond faster with full attack context
Fidelis Active Directory Intercept™ maps every detected threat to the MITRE ATT&CK framework, giving your SOC team instant context on attacker techniques, tactics, and procedures. Prioritize response, understand attack paths, and demonstrate coverage to stakeholders.
Stop Threats Early with Real-Time AD Detection
Fidelis Active Directory Intercept™ continuously baselines normal AD behavior and flags deviations in real time: DPAPI key extraction, unusual LDAP queries, abnormal login patterns, and Kerberos ticket abuse. Your team acts before damage occurs.
Detect attacks that logs miss
Unlike log-only tools, Fidelis Active Directory Intercept™ performs deep inspection of live AD protocol traffic (Kerberos, LDAP, NTLM, and SMB), catching techniques that leave no event log trace, including pass-the-hash, overpass-the-hash, and LDAP reconnaissance.
Expose attackers instantly with deception-driven AD visibility
Fidelis Active Directory Intercept™ auto-discovers and maps every AD entity (users, computers, groups, OUs, and trust relationships), then strategically deploys deceptive decoy objects throughout the terrain. When attackers interact with decoys, you’re instantly alerted.
Benefits of Fidelis Active Directory Security
Give Your Organization the Power to
1. See More: Full visibility into all AD objects and access paths
Gain complete visibility into Microsoft AD objects across your organization’s resources and access paths. Fidelis AD Intercept™ provides a hierarchical view of all AD entities including users, computers, groups, and domains, with detailed information on each. Low privileged permissions are required as information is fetched using LDAP.
2. Detect Faster: Catch misconfigurations and active threats before they impact you
Get alerts for AD misconfigurations and active threats before they impact your organization. Fidelis AD Intercept™ enables security teams to seamlessly catch configuration issues caused by ongoing changes in Microsoft Active Directory, gaining complete context and information about each attack.
3. Defend Better: Powerful network sensors with AD-aware deception
Combine powerful network sensors with AD configuration monitoring and automated AD-aware deception for a multi-layered defense. With full terrain mapping and risk profiling, Fidelis Deception® automatically deploys intelligent deception to stop Active Directory attacks across on-premises and cloud environments.
4. Respond Faster: Scripts and playbooks that automatically thwart adversaries
Use pre-built scripts and playbooks to automatically thwart adversaries using powerful forensic analysis tools for real-time incident response. Sensors placed strategically across your network and clouds detect, thwart, and build Microsoft security that other tools cannot match.
5. Perform Better: Threat-informed decisions with MITRE ATT&CK mapping
Make threat-informed decisions using powerful alert mapping to MITRE ATT&CK TTPs. Fidelis Active Threat Detection correlates all activities with MITRE ATT&CK TTPs, giving security teams the context needed for faster, more accurate incident response and threat hunting.

Trusted Where AD Matters Most
Active Directory is the #1 Target & Hardest to Defend
AD attacks go undetected for far too long, giving adversaries time to move freely and escalate access. This whitepaper helps you close that gap by covering:

Threat Protection Offered by Fidelis Active Directory Intercept™
AD Reconnaissance & Enumeration
Attackers use tools like BloodHound to map your AD environment using stolen identities. Fidelis AD Intercept™ detects LDAP enumeration, AD topology mapping, and stolen-identity reconnaissance, then lures attackers into decoy objects that expose their presence instantly.
Kerberos & Credential Attacks
Kerberoasting, AS-REP roasting, DCSync, DCShadow, Golden Ticket, and DPAPI key extraction all abuse the Kerberos protocol. Fidelis performs live inspection of Kerberos traffic, catching these techniques at the wire, where no event log is ever written.
Lateral Movement & Privilege Escalation
Pass-the-Hash, Pass-the-Ticket, LLMNR poisoning, and GPO abuse let attackers move silently from workstation to Domain Controller. Fidelis tracks east-west AD traffic in real time and deploys breadcrumbs on real assets to widen detection coverage across your entire AD terrain.
Technology Integrations That Strengthen Your Network Posture
Fidelis Security believes in partnering with the best solutions and platforms out there which ensures we provide our clients with complete contextual visibility into their networks.
Attackers Spend Months Mapping Your AD. You Can See Them in Minutes.
Shift Detection from Post-Breach to Pre-Escalation
The traditional detection model fails against AD attacks. By the time a SIEM fires an alert, adversaries have already mapped your domain, identified privileged accounts, and established persistence. Fidelis Active Directory Intercept™ flips this timeline: deception breadcrumbs on real assets and decoy objects throughout your AD terrain mean attackers expose themselves during reconnaissance, before they reach your Domain Controller.
- ALERT: DCSync attack detected (T1003.006) | Domain Admin targeted
- ALERT: Kerberoasting | 47 SPNs queried by svc_backup at 09:14:22
- WARN: Decoy SPN touched. BloodHound recon in progress on WS-031
- OK: Attacker identity confirmed via deception hit. Isolated.
- OK: MITRE ATT&CK T1558.003 mapped. Automated playbook triggered.
AD is where Attacks begin, and Defenses Fall Short
Detect AD reconnaissance and credential abuse before attackers reach your
Domain Controller.

Frequently Asked Questions
What is Fidelis Active Directory Intercept™?
Fidelis Active Directory Intercept™ is the only AD security solution that combines three integrated layers: AD-aware network detection and response (NDR), integrated deception technology via Fidelis Deception®, and foundational AD log and event monitoring. Together, these layers let organizations not just identify Active Directory threats, but respond swiftly to stop attackers before they reach domain-level control, across both on-premises and hybrid Azure AD environments.
How does Fidelis Active Directory Intercept™ detect attacks that SIEM tools miss?
SIEM and log-only tools are blind to AD attacks that leave no Windows Event Log trace. Fidelis Network® uses Deep Session Inspection® to analyze live Kerberos, LDAP, NTLM, and SMB traffic on the wire, catching Overpass-the-Hash, LDAP enumeration, DCSync, and DCShadow attacks before any log entry is written. Fidelis Deception® then places strategically deployed breadcrumbs and decoy AD objects throughout your environment, delivering near-zero false-positive alerts the moment an attacker touches them.
What specific AD attack techniques does Fidelis Active Directory Intercept™ detect?
Fidelis Active Directory Intercept™ detects: Active Directory reconnaissance (BloodHound, LDAP enumeration, stolen-identity mapping), brute-force authentication attempts, Kerberoasting, AS-REP roasting, DPAPI key extraction, DCSync attacks, DCShadow attacks, LLMNR poisoning, password sniffing, Pass-the-Hash, Pass-the-Ticket, Golden Ticket abuse, and GPO manipulation. All detected techniques are mapped to MITRE ATT&CK TTPs, and continuous AD configuration monitoring catches misconfigurations (kerberoastable accounts, unconstrained delegation, weak ACLs) before they become active attack paths.
