Security starts with the Logon

It only takes a careless employee to share a password or leave a workstation unattended. Even the most careful employee can be exploited and the victim of stolen credentials. UserLock allows IT teams to extend logon security far beyond group policies and native Windows Active Directory.

The Complete Security Solution For Active Directory Domain Logons

Control & Protect

Set restrictions using the contextual information around a user's logon, to help verify all user's claimed identity, and authorize, deny or limit network access. Restrict by:

  • Origin: Computer (Windows & Mac), device & location restrictions (IP address, department, organizational unit)
  • Time: Logon hour restrictions, maximum session length & session time quota
  • Session type: Workstation, terminal, Wi-Fi, VPN and IIS sessions
  • Simultaneous connections: Limit concurrent logins and initial access points
Control and Protect - Number of initial access points allowed

Detect & Respond

Real-time monitoring and risk detection tools immediately alert on suspicious logon activity so you can take action quickly.

Control and Protect - Block a user

Audit & Report

A centralized audit on all network logon events provides detailed reports to track down security threats, support forensics and prove regulatory compliance.

Reduce the Risk Of External Attacks, Internal Security Breaches and Compliance Issues

From careless to criminal – defense against compromised credentials

UserLock's contextual access security renders genuine employee logins useless to would-be attackers. It also helps eradicate careless user behavior such as password sharing, shared workstations left unlocked or logging into multiple computers simultaneously, as there is a consequence to a user's own network access.

Stop uncontrolled user access - make users accountable for any activity

Stop uncontrolled user access - make users accountable for any activity

Logins are the first line of defense for any Windows network and must be managed to ensure access is identifiable and attributed to an individual user. UserLock allows an organization to determine the legitimate access needs of each individual user, group or organizational unit, and efficiently enforce that decision (permanently or temporarily).

Frictionless security protects logons without impeding end users

Transparent to the end user, UserLock's contextual security ensures employees remain productive and are not continually interrupted with additional security steps.

Frictionless security protects logons without impeding end users

Immediately respond to logon events

Significantly reduce the time spent (up to 90%) monitoring and responding to logon events. React instantly from the UserLock console itself.

Centralized logon logoff forensics

Go far beyond native auditing with comprehensive reports on every session access event. This granular information is also easily exported and integrated into other log management systems.

Compliance starts with the Logon

UserLock addresses areas of user access security that relate not only to compliance (PCI DSS, SOX, HIPAA, GLBA, FISMA, ISO 27001, NIST 800-53…), but general good security practice.

Discourage malicious and careless user behavior

As well as out rightly restricting certain behavior, logon notifications encourage users to avoid careless mistakes and helps malicious insiders think twice before acting.
