Threat Protection

  • Anti-Phishing: Protects users from sophisticated phishing attacks by using machine learning to detect and block malicious emails. It also helps identify and warn users about impersonation attempts.
  • Anti-Malware: Scans and filters incoming emails and attachments for malware, ensuring that harmful content never reaches your users.
  • Safe Attachments: Instead of opening potentially harmful attachments, Safe Attachments automatically routes them to a virtual environment where they are scanned for suspicious behavior.
  • Safe Links: URLs embedded in emails and documents are checked in real-time, blocking access to malicious sites even after the email has been delivered.

Threat Investigation & Response

  • Attack Simulation Training: Allows IT teams to simulate real-world attacks, such as phishing campaigns, to train employees and identify potential vulnerabilities in your organization.
  • Threat Analytics: Provides detailed reporting and insights into threats targeting your organization, enabling IT teams to respond more effectively.
  • Automated Investigation and Response (AIR): Automatically investigates suspicious activities and takes remediation actions, reducing the workload on your IT team and minimizing response times.

Post-Breach Detection and Remediation

  • Threat Explorer: Offers an in-depth analysis of threats that have bypassed initial defenses, enabling IT teams to trace the source of an attack and take corrective measures.
  • Attack Surface Reduction: Proactively reduces your organization’s attack surface by identifying and addressing security misconfigurations, unpatched vulnerabilities, and risky user behaviors.

Compliance and Data Governance

  • Information Protection: Ensures sensitive data is protected by enforcing data loss prevention (DLP) policies across email and cloud services.
  • Advanced Hunting: Provides a query-based threat hunting tool that allows IT professionals to proactively search for indicators of compromise (IOCs) within the organization’s data.

I've worked with hundreds of hosting companies over the last 20 years of running a web design business and ISOC ranks at the top of the list. Their support has always been prompt, their people great and I wish I could rate them higher than 5 stars!

Stephan and his team helped me figure out what I was doing that was slowing down my machine and my experience. He was patient with me and I'm a dinosaur with technology. He and his team got back to me promptly by email and phone. excellent.

I purchased a small business and we inherited ISOCNET from the previous owner. We don't typically need much, but any time we have questions or need assistance ISOCNET is very helpful and has always thoroughly explained things to us.

One of our email addresses got compromised. A client contacted us about a phishing email they received from an email close to our domain. The email tried to get our customer to change their ACH Payment to us. ISOCNET (Tommy and Stephen) stepped up and helped with different security measures on our email and stepped up to conf call with our compromised customer to assure them all was safe and secure. They literally helped save a customer. I highly recommend them and their services.

ISOCNET checked in with me when they noted my email was used in Canada - I was using my account while on vacation to check messages. I appreciate their care in checking in with me. Customer service is key to why we've remained customers since the service began - if it's working perfectly for you, no need to switch.

We have been a non-commercial ISOC customer since the late 90's. Connectivity is second to none. Virus protection is first rate. I cannot recall ever having a virus get through. Customer service has always been responsive and supplied answers for my questions. Well done!
