What is Cloud VPN?
Cloud VPN is a technology that has been designed to help your users across your company to access your company's applications, data, and files through a website or a VPN application. It is different from traditional static VPNs, because it provides you a secure connection that you can even deploy rapidly and globally.
You have seen a dramatic rise in telework driven by the COVID-19 pandemic. It also demonstrated the limitations of traditional site VPNs. Many organizations discovered that their existing VPN solutions were unable to meet the needs of a mostly or wholly remote workforce. Hardware VPN appliances were overwhelmed, and it led to inefficient routing of cloud-bound traffic through the headquarters network. It resulted in increased network latency. Thus, Cloud VPNs have become a key requirement...it makes sense to transition your VPN solutions to the cloud as well.
These VPNs are based on 'Site-To-Cloud' Architecture, and enable your users to securely access your corporate networks and resources remotely, regardless of where your users are located on the globe. Cloud VPNs ensure that all of your employees whether they are travelling, or working from home, or working on the go, can security access networks.
Cloud VPN securely connects your peer-network to your Virtual Private Cloud (VPC) network through an IPsec VPN connection. Traffic traveling between the two networks is encrypted by one VPN gateway and then decrypted by the other VPN gateway. This action protects your data as it travels over the internet. You can also connect two instances of Cloud VPN to each other.
Cloud VPNs can also be called VPN as a Service (VPNaaS) or hosted VPNs.

What is UEBA?
UEBA stands for User And Entity Behavior Analytics.
USER + Entity
Modern cybersecurity solutions strive hard to monitor the behavior of human users (your employees, customers, partners' employees, etc). They go even further and monitor the behavior of non-human 'ENTITIES' too, that means they are capable of monitoring 'machines' also.
For example, on day if a given branch office of your company, suddenly starts receiving 1000s more of requests than usual, then there is very high-likelihood that your IT administrator might not notice this, as a potential DDoS attack. But your UEBA would surely recognize this enhanced number of incoming requests and take some pre-defined action.

Most networking guys know that when they create WANs, they rely on actual physical routers to connect their remote or branch-office users to applications which are hosted at corporate data-centers.
You already know that each router has a data plane which holds the information, and a control plane which tells the data where to go.
Where this DATA will flow, it is typically determined by a network admin/engineer...They will write some certain RULES and POLICIES for each router on the network. Since this process of defining rules and policies is performed 'manually' most of the time, it is time-consuming and error-prone.
Your WANs depends on MPLS, wireless, broadband, VPN, LTE, VPNs and Internet to get connectivity to corporate applications, services and other resources.

The data is at the heart of whole IT and is the chief concern of cybersecurity…
Your company data consists of its intellectual property (IP), financial info and personal identifiable information (PII) of your customers and employees. All data that is confidential in nature, it vulnerable to attacks from cyber-attackers. There are so many potential issues which may expose your important data to outside world.

First, let's consider the true picture!
The overall landscape of emerging cybersecurity threats has gone extremely wide and deeper in recent years. Almost every enterprise, large or small-medium, is severely under-pressure to protect its critical information and data. Every organization which has been attacked in recent years, had to pay a huge cost of their cybersecurity vulnerabilities.
More than half, i.e., 53% of all attacks resulted in financial damages of more than US$500,000, including, but not limited to, lost revenue, customers, opportunities, and out-of-pocket costs.

What is a Port Scan?
A port scan is one of the fundamental technique that is used to identify the open doors or weak-points in a network. Network admins use this to discover the potential vulnerabilities by sending packets to specific ports and analyze response. You can use tools like IP scanning, Nmap, Netcat, etc. to ensure that your network and systems are secure or not.

WHAT IS REMOTE ACCESS?
Remote access is the ability for an authorized person to access a computer or a network from a geographical distance through an internet connection. It enables your users to connect to the systems they need when they are physically far away.

What is QoS?
It is Quality of Service.
You would always want a kind of guarantee that--your network would be able to run all those applications that you assign as High-priority applications, as efficiently & reliably as possible. You would want that all the traffic to/from those high-priority applications gets first priority, even if your network is facing any type of limitation, e.g., network congestion. You can achieve this virtual guarantee with QoS - a set of technologies which work in tandem for your network.
