Corvid Intelligent Cyber Defence
At CORVID (part of Ultra), we deliver advanced and innovative IT security, discreetly. We provide best-in-class monitoring, intelligence, protection and remediation services. We offer the peace of mind that effective IT security brings to those that do not have the staffing and specialist infrastructure to deliver it themselves. The scale and nature of cyber security threats are largely misunderstood, even by vendors and experts with many years' experience. Threat actors are intelligent, educated, and highly motivated. They are well-informed of the tools and techniques commonly used to detect their activity. Often, malware demonstrates a level of sophistication far exceeding any anti-virus technology currently available. If these sophisticated attackers were only targeting well-protected government institutions, this would be a difficult but manageable problem. But the internet means that any organisation can be a victim, either deliberately or by simply being online. CORVID was created to help organisations mitigate this threat. CORVID provides a range of cyber protection and information assurance services that can be combined to form a total defence package, or selected individually to help augment an existing but incomplete cyber defence.
