Martin Pramatarov / / Protection

Phishing attacks are a real danger for every business. It can severely damage the brand name, and it can lead to less trust and leaving of clients. The attackers can spam or phish with emails that use your brand logo and looks just like your emails. Even you won’t see a difference between one of these fake emails and the original emails sent from your servers. We have already talked about SPF and how it verifies the outgoing mail server. There is also another DKIM technology for signing emails. Domain-based Message Authentication (DMARC) uses both of them to take pre-defined actions. Double protection for lowering the chances of phishing and report system for better management.

The “fluffiest” and biggest cloud which is leading this revolution is the Amazon Web Services (AWS). AWS is an IaaS and a PaaS provider, but to better understand it, let’s see the main components.

Cloud computing trends that will improve our businesses

Martin Pramatarov / / Cloud Computing

Cloud computing, 10 years ago it sounded like a futuristic dream, now it is present daily in our lives. In different ways, we all use the cloud, for storage or processing.

What will be the next significant trend in the cloud development?

Cloud computing

Let’s first define what it is. Cloud computing has many dimensions – cloud storage, a server, a platform for development. It gives a huge potential to the consumer or the business. It provides resources of powerful computers, in a scalable way and most commonly on a subscription base. Clients can choose the suitable plan for them and easily upgrade if they need more resources in the future.
