How Cloud-Based Email Gateway Solutions Improve Continuity
How Cloud-Based Email Gateway Solutions Improve Continuity – Phishing and spam have become prevalent threats to organizations around the globe. Cybercriminals aim to get their hands on sensitive data and sabotage your business continuity by targeting and overloading your email system. Resuming an organization’s critical functions is challenging when its service delivery processes are pummeled.
Single point of failure. Adding a perimeter gateway removes the single point of failure when using your own server, M365 or Google Workspace.
Cloud-based email security solutions have been created in response to these challenges and business continuity risks. Let’s uncover what they are, the function of email gateways, and what you get when your security mechanisms are deployed in the cloud environment.
Looking Under the Hood of Gateway Email Security Solutions
Email gateway solutions encompass various features businesses can leverage to protect their email communications. These include filtering systems (also known as secure email gateways), data loss prevention (DLP) measures, archiving solutions, and everything in between. They can be implemented as on-premises installations or cloud-based services but are unavailable as API or in-line email security offerings behind the Microsoft 365 or Google Workspace perimeter.
Within this framework, email gateway solutions are deemed necessary to prevent most threats. They represent specialized security tools that can be implemented in the cloud to analyze, filter, and block email traffic identified as fraudulent content. By performing these functions before emails are sent or received by an organization’s employees, gateways neutralize the threats that would otherwise need to be dealt with after the disastrous event has occurred.
Gateways are highly effective against phishing and ransomware attacks. Their ability to filter out suspicious emails, spot malware-laden attachments, and remove infected emails that have slipped in exemplifies cybersecurity best practices and the functionality you need for continuity.
Features of Cloud-Based Gateways
Cloud-based email filtering systems are designed to be feature-rich. The cloud environment is perfect for enriching the protection capabilities of gateways for:
- Advanced threat detection. Gateways can be implemented as a cloud service enhanced by ML and AI algorithms. These contribute to improved protection against fraudulent software or content in emails by expanding filtering functions for a variety of suspicious patterns.
- Real-time filtering. You don’t have to run time-consuming inspections every time you email a colleague or receive a message from a potential client. With a gateway, the automated filtering and blocking processes occur in real-time, allowing you to keep up with your workflows.
- Archiving and encryption. Cloud-based email security gateways often have a robust adjacent architecture to cement your cybersecurity. Integrated archiving and encryption are only a few additional features that can help with risk prevention and mitigation.
- Threat intelligence. Awareness of what type of cyber attacks your organization is subjected to and which users are targeted most often paves the way for identifying your cybersecurity needs and the practical methods of fulfilling them.
You can get a similar range of features, regardless of whether you go for cloud-based gateways or have physical appliances behind your email network. The key differences between these deployment types are scalability and cost-effectiveness. Cloud solutions provide more leeway for adjusting filtering and archiving functionality based on real-world email traffic and organizational needs. They allow you to scale up or down security resources without physical infrastructure constraints.
Cost-wise, cloud-based email security solutions are easier to budget for at the deployment and further stages. Because you do not have to cover the cost of an on-premises server and servicing that will be required down the road, cloud security is never tied to an onerous financial burden. Monthly or yearly subscriptions mean predictable costs and no concerns over server maintenance.
The Dangers of Inadequate Email Security on Continuity
No matter the industry, businesses face multiple risks that can derail their operational resilience. These risks are even more numerous and crippling if an organization has no email gateway solutions in place or has insufficient security that fails to capture a malicious attachment disguised as a purchase order. In this case, it’s not uncommon to find yourself dealing with:
- Inability to conduct business operations. A successful malware attack can paralyze entire departments. Whether you are a healthcare provider, an insurance company, or an investment firm, extensive downtime can lower your position in the industry and make clients or partners hesitant about working with you.
- Loss of confidential data. If sensitive data is stolen due to a cyberattack, you may have difficulty providing your services. Worse yet, a complete halt may be inevitable when you have no idea what data has been stolen or what email accounts have been compromised.
- Regulatory consequences. Continuity is more than just a “nice-to-have” guarantee for business operations. Continuity compliance is mandatory in many industries, meaning that the failure to ensure it results in financial penalties. These are often exacerbated by the costs of remediation campaigns and legal defense.
Having inadequate email protection is like treading on thin ice. Gateways and other security solutions are required to nip cyber incidents in the bud and facilitate recovery efforts. An organization’s inability to swiftly get back on track can extend the duration of disruption and amplify its impact on the business.
Therefore, the remediation features of cloud email security solutions are of paramount importance, too. If a threat has not been intercepted, you’ll want your protection systems to automatically delete harmful content post-delivery, analyze the extent of damage it has already caused, and inform your response teams of the incident. You should implement cloud solutions with redundancy and failover capabilities to maintain continuity during or shortly after the attack.
Email Gateway Security Best Practices
The best results for email security and continuity can be achieved by teaming up with a trustworthy and tech-savvy vendor and taking recommended implementation steps. You should do the following to ensure your email network is adequately protected:
Conduct a General Assessment
Before deploying a gateway, you should get familiar with its spam and malware effectiveness as well as additional filtering and remediation features. Consider whether it adds additional value over services such as Microsoft 365 Defender and Google Workspace natively. Most vendors should have efficacy (detection rates) reports prepared by independent analysts to share with you. Additionally, review a vendor’s commitment to roadmap updates, uptime and general maintenance. With many acquisitions in this space, technologies with reputable names have lapsed in development and support over that past few years.
Analyze Compatibility
Gateways have different compatibility restrictions for security information and event management (SIEM) systems, email platforms, and file-sharing applications. You’ll need to deploy one that works flawlessly with what you currently use and allows for customizations and add-ons. Most vendors will work with a network of specialist technical partners and distributors. Review the partners and decide if traditional distribution is correct for your business – In most cases the independent technical specialists are the best option for hands on white glove services.
Add Scalability to Your Set of Priorities
Scalable solutions are important for reliable protection and cost efficiency. Yet, the scalability potential is not a fixed value. When you dive into email security gateway comparisons, evaluate each in terms of how it can be adapted to skyrocketing traffic or additional compliance requirements. Think of this as an integral part of research to understand your options when organizational needs change.
Take Reporting Seriously
Centralized reporting can help you fine-tune corrective actions after a cyber incident, identify potential compromises, and avoid legal issues. Ideally, you will want this feature coupled with predictive analytics to reinforce your preparedness to tackle email threats.
Test It
A free trial version is a practical way to assess the effectiveness of cloud-based security solutions before the full transition. You can engage your IT professionals and compliance experts during the testing phase to determine whether all requirements are addressed.
Develop a Response Strategy
Having an advanced gateway and a range of other security features behind your email network is forward-thinking, but you can’t rule out the possibility of being hit by malware. For enhanced cybersecurity and continuity, it’s vital to have a response strategy for different cyber threat types, complete with specific procedures that must be carried out to limit the impact of an incident and restore your organization’s operational capability.
