The adjective 'wachsam' (vigilant) is closely related to the verb 'wachen' (to keep watch). The ending '-sam' expresses a quality or tendency. 'Wachsam' therefore literally means that someone has a tendency to keep watch and pay attention.
Ein guter Hirte ist stets wachsam, um seine Schafe zu schützen.
A good shepherd is always vigilant in order to protect his sheep.
'Wachsam' (vigilant) is often used to describe an attentive attitude. Typical combinations are 'ein wachsamer Blick' (a vigilant look), 'wachsame Augen haben' (to have vigilant eyes), or the instruction 'wachsam bleiben' (to remain vigilant).
Die Polizei bat die Bevölkerung, wachsam zu bleiben und Verdächtiges zu melden.
The police asked the public to remain vigilant and report anything suspicious.
If you want to express what the vigilance is directed toward, the preposition 'gegenüber' with the dative is often used.

One should be vigilant about new online scams.
