| Author info | Rating | Review Summary |
|---|---|---|
| Chief Information Security Officer at Abcl | 4.0 | We use Cisco Secure Email to protect against malicious email links and threats, valuing its integration with Cisco Talos for fast attack detection. However, it occasionally produces false positives. We considered Proofpoint but were limited by data center locations. |
| Systems Engineer at a non-tech company with 51-200 employees | 4.0 | I have implemented Cisco Secure Email, especially Email Threat Defense, which is highly effective for Office 365 users in detecting phishing and spam. However, the Email Security Gateway's interface needs improvement, and integrating both products could enhance overall email protection. |
| Director General at Icdc | 3.5 | We use Cisco Secure Email mainly for filtering internal and external messages in our Office 365 environment. While it enhances security, the pricing could be improved. We're exploring alternatives like Barracuda and Microsoft Defender due to their integrated features. |
| Cloud Partner & Solutions Architect at a tech vendor with 1,001-5,000 employees | 4.5 | I used Microsoft Azure Cosmos DB primarily for email security by integrating it with other services like Postfix, implementing antivirus, IDS, and IPS policies, though the user interface could be enhanced. I'm unaware of the product's return on investment. |
| System Administrator at bluegr Hotels & Resorts | 4.0 | I use Cisco Secure Email as an email gateway for our company's security, valuing its malware protection. I wish it had AI features for fraudulent email detection. The product isn't cost-effective, and I haven't seen ROI benefits. |
| Information Security Specialist at City Of Hamilton | 5.0 | Cisco Secure Email initially aimed to combat spam effectively and has been a valuable investment. Its features now include Data Loss Prevention and phishing protection. Despite excellent spam controls, the interface for managing email access lists could improve. |
| Information Security Specialist at IHV-Nigeria | 3.5 | My company, a service provider, uses Cisco Secure Email to secure emails, systems, and endpoints in our data center. The tool's ease of use is its most valuable feature, though improvements are needed in its architectural setup, particularly in simplifying SMTP route configuration. |
| Senior Network and Security Engineer at Symbol Technologies PLC | 5.0 | I use Cisco Secure Email to protect email communications and integrations, especially with Microsoft email services. While it's a valuable part of Cisco's cybersecurity offerings, the high cost may not suit everyone, with competitive alternatives available. |
