Cyber Security has become essential for all

"Because of the rise of remote working, cyberattacks have grown exponentially in recent months, with the FBI reporting a 400% increase in complaints in April versus March, as attackers hope to expose weaknesses in an organization's business continuity strategy"

Fundamental difference between some of the biggest cyber-security companies:

CrowdStrike's (CRWD) endpoint protection uses resource-friendly security agents to inform its crowdsourced cloud about any potential threat anomalies. All customers are protected based on a single threat found, and its technology is supported by having renowned threat remediation and hunting capabilities.
OKTA disrupted the identity access and management market with its cloud-based technology that has a large number of application integrations that make controlling who has access to what much simpler for security teams. In a perimeterless security world, the importance of identity is becoming paramount.
Zscaler's (ZS) secure web gateways delivered via its cloud locations provide customers a safe route to cloudbased resources. Branch and remote users can go directly to their applications instead of going through a centralized data center, decreasing lag for the end user and alleviating traffic bottlenecks for IT teams.
Palo Alto Networks (PANW) is an attractive option for investors. In our view, its cloud transition springboarding growth off its firewall leadership, upselling and cross-selling prospects via its security platform, and strong cash flow and balance sheet are being overlooked for the pure cloud-based companies.
